A few weeks ago, we successfully got rid of our 7 month old ds dummy which had been a real problem during the night = popping back in every hour, hour and a half. He's now doing really well without it, except he now wakes around 3 am and chats and makes noises - very loudly and high pitched. He's not crying or distressed and eventually an hour later goes back off. However he is waking the entire house - not great for 12 year old dd who has to go to school and dh to work!!!! He then stirs for 10 mins at 5ish and then 6ish!!! We dont go in to him as he's not upset and just leave him, but its really taking its toll on all with very disturbed sleep. What can we do???
