D's has always had a bedtime routine (tea, bath, walk,a story, breastfeed, bed). He goes to bed still awake and settles himself very quickly. The problem is he doesn't stay asleep very long. He wakes screaming and won't resettle until he is picked up and rocked or breastfed. He does this roughly every 20 mins-1.5 hrs, throughout the night, sometimes taking hrs to resettle. We put him to bed at 6.30, which is because he won't take a beaker or bottle and I go to work in the evening (so feed him last thing before I leave). He often won't go back to sleep at all after 4am, even though I have never taken him downstairs before 6am. During the day he often has a 30 min sleep around 9 (but only in the car or during a breastfeed, which he wakes from as soon as the car stops/I move), and sometimes again for about 30 mins when I am on the school run.
I have tried cc but he will cry hysterically for hrs and gets in such a state he vomits, if he isn't picked up. This makes him even worse for the rest of the night, with him immediately screaming as soon as we move to put him down. He is dc5 so I don't have time to rest during the day and am seriously struggling to function most days.
We are happy to co sleep and do so with dc4, but he doesn't sleep any better even suckling all night. He wakes, sits up and starts screaming and crying, seemingly for no reason. I don't think he is ill or in pain and he sleeps no better if he has had Calpol.
Desperate for more sleep (I average a total of about 4hrs in every 24). Any ideas or suggestions gratefully recieved.
