Since the start of June my 15 month old has been waking at least once per night. She has been sleeping through mostly since we did CC in December last year. I feel like I have tried everything and it seems to be getting worse, not better.

She (and we) had a period of illness when she was so unhappy (or I was so sick) we took her in our bed. I thought she would go back to sleeping through when she got well, and when she didn't, I thought she was teething. Then I thought she was too hot in her new winter pyjamas, then I thought she was too cold as the weather cooled. Now I am trying giving her water at night in case she is dehydrated in the dryer weather. I've tried settling her in her cot and not taking her in our bed, I've tried getting DH to rock her to sleep.

Last night was the worst with about 2 hours of screaming tantrums. I was so mad with her this morning I couldn't talk to her. She is in child care now and wouldn't say goodbye to me this morning.

Please help! Has anyone had this happen at about this age? Maybe between 1 and 2 years? Do you have any advice?
