Since the age of 10/11 months he has woken 5 nights out of 7. At different times, sometimes once a night, sometimes loads of times in one night. It's killing me.
He settles himself to sleep in the evening. When he wakes in the night he cries, we go in, say ssh, occasionally rub his back or rearrange his covers. Unless ill or teething, he immediately goes quiet and we leave. We're only in there for about a minute and we leave before he goes back to sleep. He had a lot of illnesses over the winter and has only recently outgrown (we think) bad reflux.
He has a nap after lunch about 1.5-2 hrs.
When he doesn't sleep well at night (Say 3 wakings) he will wake up early (6) and be grouchy all morning. The few nights he does sleep well he wakes at 7 and is an absolute angel.
Any clue whatsoever about what could be causing this and what we can do to make it stop??
