Girls, we're two weeks in, the schedule is like this: we get up every 2.5-3 hours. During the day we sleep pretty well, but at night we might not sleep for 3 hours from feeding to feeding, crying and fussing. It seems like everyone writes and says that it's very much awake for a long time, should be awake for two hours throughout the day. But we only have three hours of wakefulness at night, maybe some calming drops? Who can advise something?
