How much milk is your baby eating in a day?

How much milk is your 3/4 month old eating in a day?

My babe is getting 3 oz every 3 hours so sometimes that’s not even 1oz an hour (only 19ish oz per 24 hours). He is on kendermil and we switched him from cow and gate because that gave him a bad tummy. But now I feel like the lender I’ll didn’t even help.
