help 9 month waking every 2 hours in night

[mummymic]

please help - my ds2 has never really slept through (oddity after ds1 and dd who both slept through from 6 weeks!) but this last week he has got even worse - he is waking every 2/3 hours (about 4/5 times)i have tried giving him his dummy, then water and finally when he has been up for an hour i give him some milk - he has about 3 oz and goes back off for another couple of hours
he is still in my room as he will be sharing with dd (2.6) and she sleeps really well (7-7or8) even if i get hiom in my bed he still doesnt sleep
he has just cut his top 2 teeth but even before then he wouldnt sleep through
any ideas anyone?

has he a sleeping bag?

forgot to say i refuse to get up before 7.30 so he comes in my bed from about 6.30-7

[mummymic]

he does sleep in day - about 2 x 20/30mins
he goes to sleep all by himself but he is a wriggler/fidget in the night - he goes to bed about 6.30-7.30
he will sleep either on tummy on side or on back!

does he sleep in the day?

does he sleep on his tummy or back?

what time does he get up?
