I'm a student who spends about 7 hours away from my baby every weekday. During this time, there are days where he will not eat until I get home. He will scream and scream until I get home to breastfeed him. We've tried so many different bottles, formula, breastmilk. The closest we've gotten is feeding him breastmilk with munchkin latch bottles which has helped tremendously but there are still days where he refuses to eat even when he's hungry. Any advice ? 🙁
