Feeding

Rachael
I dunno what im doing wrong. My baby is 5 weeks old and is already at 7 oz. He seems to always want food. I try a paci or putting him in a bouncy etc before feeding and diaper too of course. I still feel like Hes over eating. He has grown almost 4 inches since birth. Anybody else going through this? Or been through this? Hes not even spitting up but once in a blue moon. No throwing it up. So dr says Hes fine. But i think im just afraid of over feeding him.
