My 7 month old son who was born 10 lbs 4 oz has never slept through the night.He wakes up at 7.30am only has two twenty minutes naps during the day and starts getting tired around 8pm... he may sleep for an hour then he wakes up for an hour and so on. He just never seems to get into a deep sleep. I don't believe its hunger that is the cause since he doesn't want milk in the night and he has been taking solid food successfully for a two months. The slightest noise wakes him up such as switching a light switch off outside his room. I have tried absolutely everything from adding a blanket to his cot in case he is too cold to keeping him awake all day so he'll sleep but nothing seems to work. He is such an active baby and needs alot of stimulation. He is always on the go. If anybody could advise I'd be most grateful... I need SLEEP!!
