Confused w 4 month old

Alyssa • ♡Boy mama to River♡

My baby boy in the past few weeks or so has suddenly started to take breaks during feedings. He was up to 6oz and didnt for a little bit when I bumped up the oz of formula and he eats every 2 hours which I wish was a little longer than that. Also the past few nights he has been up off and several times and sometimes doesnt even want to eat when he Is up.

Anyone experience this?? Going to email doctor.
