I have a 20 month old dd who is driving me to despair. she has a bath drink bed routine and did go through a stage of sleeping 10 hours solid but recently she is refusing to go to bed. She keeps getting up and when I take her back she screams. If I stay with her she is fine and will go to sleep but wakes quite alot. What can I do to get her to go to bed alone without all the screaming (from her and me)???
