Dd is 15 months old and since she turned about 11.5 months, she has started waking at night almost without fail. She previously slept through the night from about 8 weeks and always settled herself, went down awake, etc.
I have tried everything from giving her a more filling evening snack, calpol, leaving her cry, giving water, changing nappy, etc. I don't turn on any lights or talk to her, I just pick her up and sit and cuddle her until she's sleepy again. This sometimes takes 2-3 hours and I'm working and on my own most of the time as DH works shifts. I am getting desperate. Any advice please?
