Chunky Baby??

Samantha
Is my baby fat? I get worried because he has arm & thigh cub that he's over weight. He weighed 9.10 at birth, delivered 41.3 weeks and he was born on 7/6/16. At around 2.5 months he weighted 14lbs. He is combination feeding (all bottle) & he will eat 8oz every 4.5-5.5hours sometimes longer.
