My DD, 16m, has never slept through the night - once slept until 5am but usually goes down around 7.30, wakes around 9.30, we give her some water and her dummy and she goes back to sleep then wakes again around 10.30-11.00 which is our cue to go to bed and she comes to bed with us - there is no way on earth she will stay asleep if we settle her in her cot at this time (she'll go back to sleep and wake again and again at 2 minute intervals).
We don't mind co-sleeping as she wakes 4 or 5 times a night for water (and we love being able to cuddle with her), but she insists on pinching our arms as she's falling asleep. It's quite painful and doesn't seem to be normal behaviour. We've tried encouraging an attachment to a toy but no interest.
Any advice?
