How much and often does your 4 month old eat?

pic for attention: My 4 month old daughter has had acid reflux her whole life and was advised at an early age to feed 5 minutes at a time more often. Now that her GERD is slowly starting to go away (thank God), she still doesn't normally eat more than 5 minutes at a time and it is still every two hours despite me trying to stretch it out which is painful for the both of us.. I have started supplementing with formula because when I pump I cannot produce anything so i was worried she wasn't getting enough breastmilk. I

like knowing how much she is getting per feed which makes formula kinda nice..When she drinks a bottle she can drink between 4-6 ounces, just wondering how much and how often do your 4 month old babies eat?
