My baby is only a week old and I cant remember what my 4 year old was at that age. But doctors have a chart that they use to compare your baby to others. I remember my daughter was in the 10th percentile at that age so 90% of babies were bigger than her and 10% were smaller. My doctor said that as long as she was in the “curve” she was fine and not to worry about what percentile she was in.

At 8 weeks he was 10 lbs 10 oz 22 inches long.

Birth weight was 5 lbs 15 oz, 19 inches.

My son was weighed yesterday. He is 12.03 lb. and 3 weeks (he’ll be a month the 30th).

My baby weighed 10 lbs 9 ounces at 7 weeks. He was born 7 weeks early though.

My son was about that. Maybe not quite as long but the weight was 14 lbs. The docs. always tell me he is a little over average in weight and height, but they did with my first son also and now he is a tiny little thing at 6 years old.
