text: is my 2 and a half year old daughter overweight at 38lbs and 37 inches tall?   i don't think so, my 4 year old weighed about 3 lbs less than that when she was 2 and a half  years old. she has grown a little be taller, and now weighs about 40lbs, but it's just right for her age. she's not chubby at all. i would say that your daughter is just fine.
