I know it seems like doubling their birth weight is a sort of milestone but is it really a good measure of healthy baby?
I mean a preemie born at 3lbs will double their weight by 6lbs! But a nice chunky 10lb baby will have to get to 20 before they double their birth weight!
So is it really a good measure of how well your baby is gaining?
Eric doubled his birth weight by 3 months but he was a huge boy.
Fierna is still about two pounds away from doubling her birth weight but she's in the 90th percentile for weight so......
Does the whole double birth weight mean anything? Or is it just a fun thing to watch for?

I think it depends on the baby...my first son doubled his weight by 5 months he was 10lbs at birth. My second baby was 8 1/2 and he doubled his birth weight at barely 3 months old.
My nephew didn't double his birth weight until he was almost a year but he was healthy and happy and looong.
Same with a friends little girl. she was born tiny and just never put chunk on.

Ry was 6 pounds 12 ounces at birth. At her 4 month today, she was 13 pounds 2 ounces. So she hasn't quite doubled her birth weight. Our ped told us today that doubling anytime between 3 and 8 months is "normal" for the "normal" sized baby. Every child is different tho..I wouldn't worry because every child is different and grows in their own way. At almost 3, my son is still only weighing 26 pounds and he was almost 8 at birth.

My son is going to be 4 mos in 2 weeks. He was born at 9lbs 9oz and he now weighs 21 lbs. He is in the best of health, just a very big boy :)

Martha you've got some awsome milk :) Eric too was 8lbs at birth and 20 at 4 months but my little Fia was 8 at bir and only 15 at 4 months! She's around average weight but to me she seems tiny!

my first daughter kaelyn doubled birth weight at 9 months, which is way behind but maecyn is 3 months and only a pound and a half away from doubling her birth weight, in the last 2 weeks she gained over a pound so im pretty sure by four months we will have met that milestone

Well, let me tell you this...

Isa and Sofia were 5 lbs each at bith. Now at 4 months Sofia is about 15 lbs and Isa about 13 lbs (2.235 and 2.250 kilos at birth, 7 kilos sofia and 6 kilos Isabella)

They were born at 36 weeks so 5 lbs was preemie. They are both super healthy and happy babies :)



So I really don't think that matters much, just like the other milestones

I see where you're coming from. Zachary was 8lbs. 9 ounces at birth so he wouldn't double his weight until almost 17lbs which is probably a ways down the road. He goes in for his 4 month visit on the 19th, and I'm guessing he's around 15 lbs. or so. I don't see what the big deal is really.

well, my son was born 7lbs 12 ozs and by 6 months he was 22lbs and perfectly healthy....and now, he's almost 2, he's still only 25lbs....so it is not exact, like i said, a guideline - not something to stick to completely....it's not based on individual circumstances so no, not everyone can go by it...that's why the dr's do the weight/growth charts on your individual child and take their challenges (ie preemie or large birth weight) into consideration.

But 20lbs by 6 months is pretty huge! Or if a preemie is only at 6 lbs by 6 months that would be a problem. Maybe it only works if your baby is between the average 6-8 lb range....
9lb one year old would be unhealthy, and a 30lb one year old is rare I think.

it's just a guideline to be sure your child is growing at a good rate. the guideline is they should have (or be close to) doubling their BW by the time they are 6 months and triple BW by 1 year. some babies won't meet the guidelines because they may be tiny and other larger babies will blow by the guideline early. as long as your baby grows at a steady rate is all that really matters.
