Hi, My baby is 15 months old, he screams and cries a lot in the middle of the night. He does that for 5-6 times (sometimes 2-3 times) in the night and does not get back to sleep until he was lifted from the bed and rocked into the arms. He gets back to sleep once he is rocked. He is on daytime feedings only and does not feed or have anything inbetween those 10 hours of sleep. Is there anything I can help him with?
