I have a friend who's baby boy was born at 5 lbs 29 oz (2.4kgs) and now weighs 42 lbs (19kgs) at 9 months. I dont think she takes him to his check ups so need some feedback on how common/uncommon is it for a 9 month old to weight 42 lbs and if she should be concerned? I know I am.

my son was 9lbs and 10oz, he out weighed his infant car seat at three months. At 9 mos he was 30.6lbs. He is now two years old and 48lbs. He seemed to grow really fast the first year and a half and has slowed down some. He is healthy.

Check ups are really important! Especially in the first 5 years of their lives. You should really encourage her to take her kid to check ups, but not in an over barring way. Talk with her about it, maybe she has some fear that she needs to talk about.

I am not sure how concerned I would be about your friends kid. That does seem to be a large weight gain. Is the kid within "normal" development? Crawling, Walking, Talking, Eating solid food?

As a nurse, I can tell you that the baby is seriously obese. It could be a health/hormone issue, or it could be the mom feeding him the wrong things. We had a 9 month old admitted into the NICU who weighed close to 50 pounds because the mom's idea of feeding him "solid food" was getting a bucket of KFC and letting him have chicken legs whenever he was hungry. We had another one who weighed about 40 pounds and had a glandular problem. The weight fell off once the doctors put him on medicine. That mom definitely needs to take that baby to the doctor immediately. Many 4 year olds don't even weigh that much.

There is no such thing as 29oz. Once you go above 15oz... it is considered another pound. (16 oz in a pound.)

If you think she isn't taking the child for checkups, are you sure she is correct about the weight... or is she guessing? Is this weight actually what a doctor TOLD her the child weighs? Or did she weigh him in the vegetable scales in the grocery store?

Did she lift four bags of potatoes and then decide the baby weighs the same?

If the baby is breastfed, it would be a little easier to believe he could be a little heavier than what the CDC growth chart recommends. WHO growth charts are based on breastfed babies, expecting a little more weight to be 'normal'

I thought I had a big baby... until I found this post! My boy is 13 months and weighs 32lbs. My pediatrician, my family doctor, my mother (who has 6 boys) and ALL of my friends agree this is the biggest baby they have EVER seen, He is wearing size 2T/3T clothes. I can only IMAGINE what her boy looks like! Is he really tall... does he have a strong bone structure? Is his father a giant? Does he appear unhealthy? Obese?

There are so many unanswered questions here, it's hard to make a judgement.





...just an afterthought... but my family doctor lets us stop in his office and weigh the baby anytime we feel like it. (NOT my pediatrician... MY doctor) but still, he lets me in his front room anytime I stop in and say hello. Do you have a doctor that would let you use his accurate scales? Stop in for a 'weight check' with your baby and your friend and then ask her, 'do you want to see what he weighs now?' It might give you a chance to see 42lbs for yourself.

That is an incredible weight for his age, and if he has never been seen by a doctor, it's a good time to get him a checkup. If your friend can't afford a doctor, try the public health dept, or WIC. They will weigh and assess him. There are some rare illnesses that can make people grow really large, and I believe one of them is a brain tumor in the part of the brain at the top of the stem. If he's as big as you say, he may need to be assessed for these things. Try to convince her to take him to a pediatrician, if you can.

Hey again, I know I've replied before but I have been thinking about your friend's baby over the past few days. There are other factors than parents's build to be considered. Does your friend breastfeed her baby? And if so how much? as breastmilk contains a lot of calories. If her baby eats breastmilk as well as solids he may get more calories than he actually needs. Also.... he is probably not walking yet but in a few months he will start and then the excess baby fat will just disappear. I know a little boy who used to be absolutely massive. As a baby he looked like a sumo wrestler although he ate normally but as soon as he started to walk/run the baby fat just vanished. Babies's metabolism have a way of regulating itself.You can encourage your friend to see a doctor for a check-up but if she doesn't want to you can wait and see if the baby doesn't get slimmer naturally with walking around.

Holy crow. That is HUGE! My son was 8lbs 12oz at birth and now is 14 months old and at 25lbs he is slightly over. I'm sure her big boy will lose weight once he gets mobile but with all that extra weight to carry around he may have difficulty getting moving! Also, no matter what his weight is she should be taking him to his check ups and is very irresponsible for not doing so. To answer your question, YES, I'd be quite concerned!

I agree with all the other mothers concerns, I have a daughter 11years, and two boys 7 years @48 pounds and 4 years @42 pounds they are both on the correct percentile per their doctors office visits. So yes this baby is overweight and I would be concerned about his health.

No there is no need to be concerened my daughter is 6 months and she is 26lbs she was born 9lb 2oz shes high up on her height charts but so what once they start walking they will lose all the weight that is excess as long as they are healthy and happy what does it matter at this stage.

And there are at least two posts that explain why she may not be taking her son in for his check ups!! If she has chosen not to have her child immunized she may be afraid to go to the Dr. To the women who siad she HAS to get his shots that is your opinion, there is a lot of evidence that proves immunizations are not as beneficial as we have been brainwashed to believe. But that's a debate for another forum!

About the child's weight and how you approach her, I think one mum got it right when she said you may have to lose a friend for the sake of the child's health. It'll suck huge if that's what it comes down to... Or maybe lead in with the question of vaccination and if she says that she doesn't take him for that reason assure her that she doesn't have to have him vaxed but he should get a regular once over just to make sure reflexes are where they should be and that milestones (other than the obvious) are being met. If you try to be as non judgemental as possible you may persuade her... Best of luck!!

She must be giving him steroids or something! My son was born at 6lb 12oz so a bit bigger than him and at 7 months old he weighs just 14lb 15.5oz!!! He's tall but I am 5 foot 11 and his father's 5 foot 10.

My son was 8lbs 5.9oz. and 20in long.. now at 6 1/2 months old and weighs 20 lbs and about 28in long... and 90% He is also taller than most kids his age... (he looks like a 1 year old should) So Yes I think that the Dr. should be seen!

i dont think he should weigh that much. my little boy is 3 years old and he only weighs 13kg and they think that is good for his age. i really think she should be taking him to the doctors as if he gets to big it could turn into health issues

what about his parents? are they large people? i know a family and the father is very tall and so is mom. the baby was 25 pounds at 5 months...which was normal for her. if your truly concerned, talk to her and have her take the baby for a check-up.

Yes, my child is off the chart in height and weight and at 9month he only weighed 25 lbs. She needs to take him to his check ups not only for weight but he needs to be getting his shots! My 4 year old doesnt even weigh 42 lbs. She needs to be careful!!!

Yes, some one should be concerned. Why is she not taking him to his reg. check ups? If it's money I understand. But if she has ins. or the money then that child needs to go to his check ups. He's already way behind on his shots.

[deleted account]

my son was 9 lbs 8oz at birth, and is almost 2 years now, and weighs about 27 lbs. My 4 yr old daughter weighs 41 lbs, and she is tall. So, YES, she should be MAJORLY concerned for his health and safety. Bones are still cartilage at that age, and can cause his bones to form wrong from the weight. Is he as active as should be? I would definately tell her she needs to take him in, cause either he is eating WAY too much, or he has a serious health problem that is underlying.

Whether or not the baby's weight is too much. How is he developing? Can he sit by himself, crawl, is he trying to walk? There are other signs that also need to be looked for. Have you been around him since birth have you seen any changes in him or the family?

Even allowing for the fact that all babies are different, that really is extremely big for a child that age. My daughter has always been either on the 97th or off the chart completely but she was nowhere near that size! She's now 16 months and just over 13kg, and has been in size 2s for months.

Sounds like something else is going on with this baby. He needs to be checked for hormonal and growth abnormalities at the very least.

well, in that case, you do have a course to be concerned. i am just not quick to jump on the 'concern' bandwagon because often some people express 'concern' based on a brief meeting or heresay!!

i think that you should seriously talk to her and see if she listens to your concerns or even comprehends them. Offer to take them both to the doctor and see what the doctor says. As some have said on the forum - it could be a medical reason and she could be feeding him right. Also, what have YOU seen her feed him - is it junk or is it food that we all feed our babies. whilst being fair - go with your own instinct. if you truly are concerned and she doesnt want to listen or get help, then a call to the authorities may be in order - just make sure that any call to the authorities is done out of true concern - there are some people out there that make reports as a malicious act that can cause problems that destroy a family.
I wish you the best of luck111

Hayley Thompson - Hi Yeah your son sounds like he comes from a family with big genes, so he was probably born a big baby. My friend's baby was only 2.4kgs when he was born, both mother and father are small...VERY small people. She only weighs about 45kgs, can't be more than 5 foot tall. The father is short and small boned. So this baby has no excuse to be this big. I worked out the baby has been gaining an average of 2kgs a month. How much do you have to feed a baby to gain 2kgs a month?

my eldest was 20kgs at 2 years of age - he is now 10 and comes up to my chin and I am over 6 foot tall - he is in the third size of mens clothes and now weighs 70kg and has a size 10 foot (mens sized) he was a year old when he was off the chart and the doc said he was obese - we come from a line of tall/big people. Tread carefully with your friend and ask her if she is concerned and offer to go to the doc with her. she may be sensitive about it - i remember being upset when people thought my son was 5 when he was 2!! She has my sympathy because it is very hard for mum and child alike!!

That baby needs to see a doctor right away!!!! A 9 month old boy in the 95th percentile would be 25lbs or a little over 11kg. This is a major cause for concern and is very unhealthy for that baby! If she is not willing to cooperate and bring the baby to a doctor then child services needs to be called. The baby would have to be about 47.4 inches long for this to be normal and I have never seen that before or heard of it for that matter. There is no reason or excuse why the baby should weigh that much!!! Dont think about how she is going to react to you telling her she needs to bring him to a doctor. All you should care about is that baby being healthy!!!!

[deleted account]

Yes i had a look around on the web and found his growth line is not at all in line and seriously if hes not being over fed he has a medical problem that could be dangerous if hes not being brought to a doctor to be checked.I would very kindly and loving speak to his mom and encourage her to have her son brought to a doc.His heart and breathing could me in jepoardy if left.To much weight on a baby is not okay if its way over without there being a medical reason like thyroid etc.wishing you the best..hope the young baby is brought to a doc.

19 kilo's would be the weight of a 3 year old boy, who most likely would be overweight depending on his height.
A 9 month old baby "could" be around 11 kilos, once again depending on his height. Each child is different but I do know that 19 kilos is right off the scales. There may be a medical reason this baby is so overweight.

Geez both my kids (I have a 2 yr old and a 9 month old) were and are only 10.5kg. Thats pretty excessive and I wouldn't be proud of having a child that size so young and my daughters a pretty big girl (on the 95th percentile)

That is excessive! When people post about weight I normally give them a link to WHO growth chart, but that is so far off the chart there is no point. He NEEDS to be checked out by a health professional, a public health / child health nurse at least.

Are you sure her scales aren't broken?? That is very very very big.

my son vincent, who is 8 turning 9 months old weighs 11kg...he's overweight, the lowest weight gain he had for months.doc told me that he's beginning to undergo self adjustment to his weight so no worries at all...but beyond 11kg in 9 months, i think it's unusual

The guidelines say roughly 68 cm and 8 kilos at 6 months old.
My 5 1/2 months old is 67 cm and weighs 7,750 kg. I'm pleased because he's healthy but people in general say he looks big for his age. But numbers can be decieving.... how big is the baby's family?? Is his dad 2 meters (6 foot) tall? Are the parents big boned? Does the 19 kg. baby eat healthily? There are many factors here so recomend her to go and get the baby checked. 19 kilos for a 9 months old does sound a lot.

My baby was born 10pounds 4 ounces - 4.64 kilos. He is now 7 months old and weighs 11 kilos. He is also 63 cms. I go to all my maternal health check ups and he is just a long and healthy baby. He isn't overweight, he was big from birth. They follow guidelines and show you charts where bubs should be in growth. Your friend should take him to his check ups and also the fact that he wasn't a big baby at birth. 19 kilos at 9 months is definately a concern.

Yes, my goodness. My granddaughter is four years old and doesn't weigh that much. Your friend probably feels she still needs to feed the baby more so he will thrive. All babies need to go in for their check-ups.

The normal weight for a 9mt old is about 19.5lbs so the baby is more than double the weight he should be

[deleted account]

Her 9 month old baby weighs as much as my 5 year old son. His weight quite abnormal. Not only can it effect his health but his physical development as well. The poor childs health is at risk. She needs to get him into a Dr. and soon.
Heres a web site that might be helpful.

um, i would think so! my 5 year old weighs 50lbs and he is the 97th percentile for height and weight. she really needs to take him to the doctor. and she needs to make sure he is eating a healthy balanced diet. there could also be something medically wrong to cause him to have this weight gain.

She needs to take him in. My son is 4 and he doesn't even weight that much. My son was born at 8 pounds 4 ounces. My boy was BIG when he was small, but he grew into himself. I think this little boy might be a little too big. Perhaps you don't want to say to her his weight needs to be checked out, I'd look him over and you can probably find some marking or something you could say he should be checked for. Just an idea. I wonder how his eating habits are.

Personally, I think she had better go see a Doctor. My son was about 25 pounds at 9 months old, and my doctor said that he was *almost* "off the charts" large - as in, he is *almost* abnormally large. He nursed CONSTANTLY day and night, so she said if he gained a lot more, we should consider cutting back just a little. Anyway, he got active and didn't get "overweight" so it was fine. Anyway, I think 42 pounds is considerable overweight for a 9 month old according to the statistics. He could be suffering from some severe hormonal imbalance, or else is not getting good nutrition!



How to approach her? I would just be really polite and say something like "It seems his weight is really unusual for his age, have you had a doctor check him out lately? Maybe he is totally fine, but maybe his thyroid or something is not producing the right balance for his body. What do you think?"

I have no idea what she is feeding him.
My 9 month old son is a little over 22 lbs. To me he is heavy and can't imagine him being double that size. But my son is a very very healthy 22 lbs 9 month old - he is still only breastfed and only eats home made vegetables and fresh fruit. For him to be double his weight would mean there would have to be something wrong with his thyroid or hormones.
I still can't even imagine unhealthy fattening foods would make a baby that size. Do you think she is talking nonsense?

[deleted account]

That would definitely concern me. My 8 year olds are only 52 pounds! My 2 year old is 26 pounds. Granted, they are all on the smallish side for their age, but I know a 2 year old that is 40+ pounds and HE is huge....

What does she feed him?
