9 month old DS has been waking persistently at 4am for weeks. We are really starting to struggle with the exhaustion. 
He is a very active happy baby. He is crawlibg and pulling up. He eats 3 meals a day and rarely has milk in the day anymore unless he seems particularly hungry or hasn't eaten much which is rare. He hasn't had a night feed or dream feed since he was 6 months old.
His current schedule is:
4am - wakes screaming and crying. Wants company.Not hungry as far as I can tell. Change nappy if necessary. Won't settle. Bring him into our bed where he leaps about, climbs the bed frame, babbles loudly, clambers on top of us, gives us a pinch etc
5am - 9 oz bottle
5.30 - short doze in our bed in DPs "nook"
6am - wakes. 5 year old DS joins us. (I lose will to live).
7am - downstairs for breakfast.
8am - 9.30 - usually a 40 minute to an hour nap at some point
11.30- 12 lunch
12 -2 ish - long nap (sometimes less sometimes a little more)
4.30-5 - tea
6.30 - bath, 9oz bottle, bed
He goes down like a dream (always has). He'll then usually wakes briefly a few times in the night but goes straight back if we pop the dummy in...Until 4am....
He's never slept later than 5.30 and only did that a couple of times. It's been worse since he had a bad bout if the pox a few weeks ago.
We may have made it worse by getting into the habit of bringing him in with us but we're so exhausted it feels easier to do that then physically get up with him. My eldest DS was sleeping til 6am at this age and we would give him a morning bottle in his room then he would go straight back down til 7.30

Any suggestions gratefully received.
