DD has turned into a dreadful sleeper. She's 18 months and used to sleep and nap great.
Now she wakes several times a night and at least once a week she is up for several hours- last night it was 1.30 until 530am and then she slept until 9am when I woke her. She has no problem going down at 7pm and naps well (around two hours) after lunch.
I can't cope with it and I'm scared there's no end in sight. Help :(
