My daughter was 6 pounds at birth. Shes 10 months now and 18.5 pounds. She is a little chunk but my son was the same way and i was the same as a baby. My son has thinned out and very lean so i am not worried about her being chubby. They both gained weight very fast and were both breastfed.

I've got a little peanut too. Cate is almost 7 months and 13 lb 15 oz.. Dr isn't worried. She moved up from the the 7th to the 10th percentile She's eating, active and healthy. However we did move her up to size 2 diapers to try and avert some explosions! It's been pretty successful so far!

My boys were/are HUGE babies.

My sixth month old was measured in the 110% percentile in length and weight. He is 25 lbs and over 74 centimetres long (29 inches). He is wearing size 24 month clothes and should be in a size 5 diaper, but I'm trying to use up the rest of the 4s. Sometimes I'm a little self-conscious of his size, but the doctors say he is totally thriving. He just started solid foods, but up to this point he was exclusively breastfed. I get comments constantly about his size and people always assume he is older than he is, so I also get comments about why he can't do certain things (like standing unassisted or using a spoon etc). It can be tiring.

His older brother was in the 99th percentile up until a year old. Now at 2.5 yo, he is exactly in the 50th for weight and 75th for height.

My husband is 6'6" and I'm 5'10. We are big people I guess.

My son is already a little chunk- he weighs 11 pounds and isn't even 2 months old yet, but he is breastfed. I've heard that can make babies weigh more than formula-fed babies. His cousin was only 15 pounds at 6 months though, and my sister's pediatrician isn't worried about his weight at all- and that kid eats a ton!

As long as they are gaining weight and not losing weight or staying the same weight, I've heard it's ok. If your baby is losing weight as they grow, that's when you should let your pediatrician know.

I will say that I babysat a little girl who was so small that when she was 4 and her brother was 2, he was bigger than she was, but that was because he body had trouble processing gluten. Once the family and their doctors figured that out, they went gluten-free, and she started growing a lot.

My little man is a chunk! He's 5.5 months and weighs 17 lbs. He's average height and weight so I'm not worried oh and he's in size 3 diaper. Every baby is different, that's for sure!

my son is 4months old and he's 14lbs3oz, they also measured him to be 27.5 inches long (i think they messed up, he was fidgeting) he wears size 2 diapers

I don't think it's a gender thing- both of my girls have been in the 50-75th percentile for most their lives My youngest weight 16 lbs at her 6 month...just prolly take after their parents as babies, that's all!

My daughter at her last appt when she was 4 months she was 14lbs 14oz and 24.5" long and they had her in the 40th percentile which is odd for me because my son was huge he was 18lbs at 4 months and over 30" long. To me I think she is small because of what I have to compare her too. I am a firm believer in if the doctor isn't worried neither am I. Its when they worry that I begin to panic.
She is 5.5 months now and I haven't weighed her since but she still wears 0-3 months in some and 3-6 months in other brands and in carters clothes she is in 6 months(for some reason carters clothes run small).

My son is already a little chunk- he weighs 11 pounds and isn't even 2 months old yet, but he is breastfed. I've heard that can make babies weigh more than formula-fed babies.

Actually it's the other way around. Formula fed babies tend to weigh more on average from what I've read.

Miles was 9lb3oz when he was born, around 14 at 2 month, 18 at 4 months, and I'm sure he's at least 20 at 6 months...his appointment is 6/7 so we will see. He gets breastmilk so who knows. I though I read that breastfed babies weigh more in the first 6 months and then it evens out or something...who knows...as long as our babes are healthly

Teddy was in the lower percentile range for his first few appointments, but has grown steadily and is at about 14 and a half pounds now, at 5 and a half months. I was worried that he was so small at first, but he's definitely catching up, weight-wise. He's still on the shorter side...I think they said 8th percentile in height at his last appointment. I'm curious to see what the stats are at his 6-month appointment in a few weeks.

My son weighed 13 lb 9 oz at his 2 month check up. He's almost 12 weeks now, but I'm not sure what he weighs. He's definitely a chunky kid. I love it!

at 5 weeks my baby boy is 12 lbs 7 oz and 24 inches long! he was 8.2 at birth

Both of my babies were almost 11 lbs at birth & reached 20 lbs by 6 months. Chunky monkeys!

It s definetly not gender related. I exclusively bf my babies for 5.5 months when I introduced solid. My son born with 7 lb 4 oz, and was hitting 20 lb by 7 months of age. My daugher was just a bit shy of 7 lb at birth and she is 18 lb at 6 month. They birthweightn was just below 50% , but climed to the 75% by the 2 month checkup and stayed their during the infancy.

My pedi said no matter if they slim or chubby, if they grow in a steady speed along their own growth curve. Even if they are on the 10th % range but following the growth pattn of that size it is ok. They see a problem if the baby dropping on the growth curve. For example a baby was 50% , then it drops to 25 it is a warning. If the baby weight drops again to the 10% curve, it is failure to thrive. However if the baby always was small and keep following the 10% curve , it is fine.

Same thing with climbing on the curve .if a baby jumps curves twice in a row, it may be a sign for over feeding.
