Girls, maybe someone had this. We're 5.5 months old. We started waking up very often at night again. We were so exhausted in the beginning of month 4. Now, she goes to sleep at 9, sleeps steadily until 1:00, eats, and then every hour, 1.5-2 hours again wakes up and cries. Without breasts, she doesn't fall asleep.
