This is a nightmare. DD (nearly 22 months) used to sleep from 7 until 7ish. She's been quite ill recently with a nasty bug and a bad cough which was waking her up at night. She's much better now but has lost the knack of settling herself back to sleep. We had 'I want Daddy/mummy/childminder'(not crying just unhappy talking) for an hour last night' from 2 until 3am. I don't know what's the right thing to do - is it like controlled crying were you just leave them so they 'relearn' the skill? It's been going on for a few nights now - can anyone help?
