My 23 month old DD will not go to sleep on her own and still needs to be held, patted and sung to. The history is that she has been sick for a lot of her life and as such struggled to sleep for a long time due to pain overnight. The medical problems have been sorted and she can sleep well when she actually gets to sleep but won't go to sleep without all of the above. During the day I either pat and sing to her on my lap until she goes to sleep or drive her around until she sleeps and transfer her into the cot when she is asleep. As such she never goes in the cot awake.
How can I change this pattern so she can send herself to sleep - in particular if she wakes overnight so she can go back to sleep? If she wakes at the moment she needs to be patted back to sleep. I want to be able to transition her to a toddler bed at some stage but I can't do that if she can't actually go to sleep in there.
Please help!! TIA
