Ds has been sleeping through the night since about 3 months. He's been in a cot right next to our bed and would usually wake once or twice in the night because he's a very active sleeper and gets himself stuck in funny positions or because he wants his dummy at about 5am onwards. I didn't mind this waking as I was right next to him and could just put my hand in the cot and move him/find his dummy for him and then go straight back to sleep.
However, now he's 6 mo I have put him in his own room and it has been a total disaster. He'll go to sleep fine as usual without a dummy and sleeps really soundly until about midnight. But from midnight onwards he keeps waking every 30 mins to an hour and crying. I go in, comfort him and give him his dumym and he falls straight back to sleep. Only to wake up again 30 mins/an hour later. I had to get up TEN times last night and his room is at the other end of the house so I am fully awake by the time i get back to bed.
Does anyone have any ideas why he is waking up like this when he didn't in our room? It's been 3 nights now and getting worse rather than better. Please help!
