Well, why is it so ? Just a cry of the soul??? My little one is 1.5 months old and has been having trouble sleeping lately. During wake time we play, walk around the house or on the street for an hour, gets tired wants to sleep. I put him to sleep quickly falls asleep BUT also wakes up quickly ? For about half an hour he sleeps. At night too he slept like that (Woke up as a zombie?) I want when the baby sleeps a bit myself ? How does your baby sleep? I hope this will pass...
