My 22 month old easily fell into the Gina Ford 7 -7 routine and has slept through the night from 20 weeks old. She has now suddenly started waking in the night and refuses to go back to sleep ( a common problem). Some nights I have been up with her for 5/6 hours. Whilst I am with her she is exteremly contented. Controlled crying hasn't worked because she is like an olympic athlete jumping out of her cot. We've now put her back in a sleeping bag, which she is more than happy with, but she can still climb out of her cot. I don't really want to put her into a big bed because I don't think it will help the situation. Does anybody have any helpful ideas that might work?
