Tell me how your babies sleep at night in two months old? How to normalize sleep? If not outside, then at home during the day we sleep for 30-40 minutes, longer than the baby sleeps! And at night, the last few days wake up every 2.5 hours. Daytime is fine, but I would like to sleep at least a little bit at night. We're on IV.
