My baby is ten months old and he has not been sleeping uninterruptedly throughout the night for almost 4-5 months. He wakes up every one hour interval and starts crying. We have to get up and either rock him back to sleep or my wife nurses him to sleep. These days nursing does not even work. We have to rock him for about 15 – 20 minutes before he goes back to sleep again and this event occur several times a night. He is feeding well, pooping well. I am not sure what is wrong with him. Initially the problem was during the night time and now he cannot sleep more than an hour at a stretch even during the day.
