how much is a 2 and a half month old supposed to weigh?

Answer 1

Average for a 10 week old girl would be between 10 lb. 12 oz. and 12 lb. 12 oz. Average for a 10 week old boy would be 11'14"-13'14". But *normal* can be above or below these numbers.

This is the newest growth charts--the first ones ever based on babies who are known to have been well-nourished. Earlier charts were based on large populations of unknown nutritional status, at a time when overfeeding was considered to be a good thing.

Answer 2

It really depends what their birth weight was. An average weight gain is between 4-8ozs per week. This is after the 2nd week since in the 1st week of life babies generally lose a few ozs (infact upto 10% of their birth weight is still considered 'ok' in terms of weight loss) - they then regain this this over the 2nd week - so at 2 weeks old they're often the same as they were at birth - but then they should gain steadily from here on in.

A rough guide at 10 weeks is..

For Boys - between 4.5kg and 7kg

Girls are slightly less than this.

Weight gain SHOULD be a gradual, steady curve - but babies rarely follow guidelines in a book - and some weeks will gain more, some weeks less, and some weeks nothing at all - it's a general pattern over time that is important.

Weight gain is also relative to length and head circumference - so even if a baby doesn't fall within a certain weight range - they may still be in the correct proportions for their size - which, like adults, come in quite a wide range. Remember that a premature baby may appear small on growth charts - but again - it's what they gain over time that is important - as long as they are growing - things are generally ok.

I hope this helps - as a reference - mine at 9 1/2 weeks was 13lbs 1oz (only a 2oz gain from the previous week, but he'd put on 8oz the week before - so an ave of 5ozs per week)

Answer 3

My daughter at her 2 month appointment weighed 11 1/2 pounds and was considered to be on the 25% for girls. My son and 2 months weighed 13 1/2 pounds and was on the 90% for weight. Usually whatever percentile your child is born on that is what they like to see them stay at as that is what I was told from one of my doctors.

Answer 4

My son weighed 7lbs 7oz when he was born. He is 2 1/2 months old now, and he weighs 14lbs, 4 oz. But every baby is different. Mine is a big eater, obviously. But it probably has to do with him being on rice cereal, his doctor put him on it due to reflux.

Answer 5

my daughter was 9lb 3oz when she was born (8days late and induced) and at 2 months she weighed 11lbs, and at an appt we just had the other day she weighed 13lbs at 3 months.

Answer 6

Babies should gain 4-8 ounces per week.

Answer 7

That really all depends on when the baby was born. If he/she was premature or over due.

All babies are different.
