Tell me, we had little breast milk and only got the milk yesterday before going home ??? Question: 1. How long did your baby eat? And how much did he sleep? For example, half an hour on the chest, one and a half hours sleep. 2. If he doesn't cry, does it mean he is full? Because in the hospital they fed us with a syringe.
