My daughter is the master of manipulating bed time and I am embarassed she sometimes has me dancing around like a monkey before I realize it. No one ever said these kids were not extreamly smart. But we started a bedtime ritual with clear boundries so she knows what to expect. I give her a cup with about 1/4 cup potato milk after she drinks this she knows she can only have water. She still likes to sleep with a movie (I know how terrible this is) But the rule is once we have said prayers and good night any additional request are met with a warning that the next request will result in the Movie being turned off. I follow through even though when this happens I know we are in for a terrible fit sometimes but that warning is something she knows will really happen so we don't have to many bad nights. This ritual is the same no matter who puts her to bed myself my husband (who is also away alot army) or the baby sitter. She sometimes wakes very early but we told her to play quietly in her room until we wake up sometimes she does sometimes she doesn't fortunately this isn't so often.
