Baby feeding schedule

Jada

Hi moms! So my baby boy just turned 3 months yesterday. My baby is drinking 4.5-5 Oz every 2-3 hours of breast milk (I’m exclusively pumping) but I don’t think that’s normal. He does spit up a bit so I am worried that I’m over feeding him. I’ve tried to push his bottle time as long as I can but it seems like after 2 1/2 hours he’s very fussy for more milk.
