I know all babies are different and what not. Buuuut how much was your baby eating at 4 weeks? Kamila drinks 4oz every 2-3 hours. Usually it's every 3 hours but lately she's been waking up every 1-2 hours hungry. & what is a good way to get baby to sleep through the night so the baby won't be waking up every 2-3 hours. I know she's still young but for the future!
