Our 2.5 year old DD has problems sleeping. Until she was 1.5 she co-slept with no problems but then I saw expecting another baby and so she moved into her own room, where she has remained since. She never ever sleeps through, waking most nights on several occasions. Sometimes it's because he dummy has fallen out and other times there doesn't appear to be any reason. When she wakes she screams until someone attends (tried ignoring this but no use). Not sure what to do to get her to sleep bette or lose the dummy. Any advice would be appreciated.
