You often see breastfed babies who are chunky from about birth to 6 ish months and then a breastfed baby tends to slim down. They tend to gain quickly in the beginning and then kind of level out. That's why you have so many drs getting concerned about a baby falling off their "growth curve" at 9 months because their charts are based on formula fed babies and a formula fed baby tends to follow the same curve until a year.

Of course this isn't always true and you can have a super tiny breastfed baby or a super chunky formula fed baby.

Both my babies were formula feed and both were little fatties with lots of rolls til about 10 months or so. My 4 year old is now slim and healthy looking but weighs 25kgs - he is tall. I think it has a lot to do with genetics as I was a breastfeed baby and going by the photo's both my boys look exactally like I did. Also my son and niece are the same age (9 months) and my son who is formula feed is much larger then my niece who is breastfeed.
I just wanted to say that I have never made my babies finish a bottle - they always finished when they had enough.

Hope that gives you a bit of info :)

It's so hard to tell, though I've always seen the opposite. I only know a handful of bf'ed babies, most of my family and friends FF. They are usually a lot bigger than my kids..

Although, I know that bf'ed babies can be chunky until about 6 months or so, and then they'll thin out.

I also think it depends on the kid and I think that genetics can play a factor as well. I have 3 kids, all of them breastfed. All of them are tiny. My daughter's in the 25th percentile and my twin boys are in the 5th and 10th percentiles..I chalk it up to genetics, my husband is small-5'8 and 135 lbs.

My son has been over the 100% since one month old. He is tall and heavy. Yes he didn't gain much between 6-9 months but he stayed over 100% in both height and weight. Now at 1 yr he is in 95% in height and 87% in weight. He was ebf til 6 mo and eats very little table foods. He nurses at least 7 times in 24 hrs and hr is BIG! I was big too and I was not on any formula either. So generally bf are smaller but not always:)

Both of my sons i've noticed are bigger then the formula fed babies i know. My 2 month old is almost 15 lbs. I have people telling me all the time how big he is for 2 months. And i always respond, its cause he gets nothing but the best! My family cant believe how big he is. My fiance and I are tiny. I'm barely 100 lbs and he's like 125.

According to doctors, and the research I did BF babies are supposed to be smaller than FF, but...every BF baby I know, including mine, has been bigger than the FF ones.

The World Health Organisation recommends doctors use the growth charts for breastfed babies as the norm for child development. Using charts developed from the unnatural growth rate of formula fed babies led to many breastfeeding mothers being misinformed that their child was failing to thrive when they were in fact normal. Formula fed babies can tend to be overweight due to an excess of nutrients due to the tendency to overfeed them by making them finish a bottle even if they are not really hungry. This is why they are at greater risk of obesity and diabetes. Whereas a breastfed baby just stops when they have had enough. The build of the parents also need to be taken into account that may also explain the size difference - my son when he was born looked bigger than many 3 to 4 month olds, but now he's 6 ft 6 which is in keeping with his original growth rate. Just makes it very difficult to find shoes that fit!

I have two boys who were each breastfed. They were each in the less than 10% range for height and weight. But, for the first bit, until teething and solids, kind of round-ish. After that, they started slimming down. When the second go mobile, he freaked out the pediatrician.

It really all depends on the kid. Also, how did you or his dad grow? That can be a pretty good indicator.

Depends on the baby more than anything. Feed 3 babies now, first on 50% the whole time middle top 3% still a big child and my 11 month old who the bottom 20% but was a premie. I been told my dr's that formula babies are often bigger as over feed.
Breast feed babies are often happier and healthier.

I think often breastfed are bigger bcause they are happier and adjust to their milk better...all the best

i think it just kinda depends on the workings of your body and then your baby, when my son was EB he was smaller then what the Dr. thought he should have been so they had me supplement w/ formula (which was a huge mistake as he ended up weaning way early) so it just kinda varies baby to baby and mommy to mommy as far as I can tell
