DD, almost 10 months, has been waking up in the night for the last 3 weeks. For the first week I settled her quickly with a bottle, then decided to give this up, not being strictly necessary. For the last 2 weeks she´s been awake, normally for around 2 hours at any time between around 1.30 and 5.30am. None of our efforts to help seem to help her and DP and I are completely exhausted. What can we try? She settles herself to sleep at all other times.
