Dd1 is 18months, and the way we do bedtime is she has milk, settles herself with dummy and teddy and goes to sleep. I then fill a bottle and put it in the corner of the cot when I go up to bed for during the night. The trouble is that she's waking more and more often for even more milk than we put in so I'm getting up just as much. It's not like she needs it now is it?? Should she be sleeping through? How can I fix this?
