These babies are adorable! What a great age for baby pictures. The one in the bath/sink mmmm priceless!
OP I think your baby is the proper type of chunk! Adorable baby chunky.
As for the girl babies, I have a smallish girl baby too...at least compared to the girls in my due date club (feb). So it was good to see some little girlies here. She was in the 50th percentile and weighed 12.13 oz at her 4 month appointment / 17 weeks (she was 8.12 at birth). Her legs are chunky yummilicious...
