How much to feed 4 month old daily?

Amy • Married 4/4/2012. Baby #1 born 3/18/17 💙! Boy/girl twins due 2/18/20!

My baby wants to eat, like, all the time. I'm scrambling to keep his daily amount under 32 oz but it's such a challenge!! He wants a bottle every 2 hours now and wakes up at least once a night for a feeding. We give him 4 oz at a time.

How much does/did your baby eat a day around this age? TIA!
