Can you overfeed? πŸ˜•

My little one is just shy of 4 weeks and he seems to have a ridiculous appetite lately. He was eating 2-3 ounces at each feeding but today he has been so fussy and after trying everything else I tried giving him more and he seems content. Can I overfeed him though? From 5-8pm he's had like 7 ounces... I'm a first time mom and could really use some insight.
