My daughter was 10lbs8oz and 22in at birth and was 21lbs and 29in at 4/5 months old (she has since stalled growing and has not grown or gained any weight). I feel like my friends with smaller babies hit these milestones SO much sooner than she did. I have a friend with a tiny 6 month old who is already WALKING. C isn't even really crawling yet (just army crawling). Another friend had a large baby girl and she was very slow to hit gross motor milestones also.

Do you find that your baby is slower to hit gross motor milestones? Do you think their size is a contributing factor?

I was just curious about the correlation.
