What's the average weight for a 3.5 month baby boy?

[JaniceT]

Hi ladies, I'm a tad cautious these days, watching my baby's growth carefully. Need to know what your baby boy weighed at 3.5 months and his height? Mine was 20lbs (9.1kg) and 67cm. He's fully breastfed. Am worried he's growing way too fast?

my son between 13-14 lb. not sure about length.

At 12 weeks/3 months he was 12lb 7oz. His birth weight was 6lb 6oz but they're all different so not sure what you'll take from this.

He's Formula fed and has reflux but this has never stopped him gaining weight.

my LO is 18lb 5oz at 1 year!!
At 3.5 months he was about 11lb 4oz

Oh dear. This means my LO is way over the avg. weight. When he was 6wks, I was concerned of his weight gain. Now he's put on so much, so fast. I hope it isn't some hormonal dysfunction causing it.

Mine was around 17lbs at 3months. Babies at this age usually know how much milk they need, you can't over feed a baby. Weight will most likely slow down in a few months when he is legging it round the room lol

I very much doubt it chick, some babies just weight on faster or slower than others, it doesn't usually mean anything's wrong

My wee man is 13lb and about 63cm. What centile line is your LO on?

i looked in the red book... he'd be on the 99th percentile. what did he weigh at birth???

 

[thedog]

Also sorry hijacking the thread lol. My little man was on the 75th at birth, then on the 99.6th at 4 months, now at 10 months on the 91st.. so it can slow down.. x

He was 8lb 4oz, average baby size. We're Asians by descent and known to be of smaller frame. Hence am wondering why my baby looks like a Michellin Tyre mascot.

My daughter will be 3 months on Thursday and is 11lbs 12oz.. exclusively breastfed.. she was 6lbs 14oz at birth.
I wouldn't worry about him growing too hard, every baby is different!

My girlie is on the 75th percentile, she weighs 14lb 1.5oz, and is 66cm long, she is 16 weeks tomorrow, she was 7lb 12 at birth

Leo is 16lb and now 3 months...was born 9lb...

At 3 months my LO was 14lbs 12oz, not sure about height x

My little man was 14lbs at 10 weeks and measured 60cm he was 8lbs4 at birth and 55cm He put on a pound in a week but in my defence I had fed him about 30 mins before weigh in.

My son was 14lb approx at that age; but I wouldn't worry; some babies especially bf ones put on absolutely shocking amounts of weight at first. I think if my two middle boys didn't have underlying allergy problems they would have been off the top of the charts at your LOs age and would have gained considerably more per week than the 10-16oz (sometimes up to 22) they were doing and they wouldn't have had that dip in the middle months.

at 14 weeks Ava was 17lbs 11oz- she was 65cm I think??? she was 59cm when born and 9lbs 9.5oz- she totally slowed down in her growth since then and is about 21lbs now at 28weeks

At 3 months my little guy was 15lbs and 25 inces, he was born 9lbs 5ozs and exclusively breastfed. His weight has slowed down alot and he is still breastfed. At his 4 month appt. he was only up a pound.

Roughly 14lbs, he was 9lbs at birth
