Perhaps this makes me an ineffective babysitter, but I can not walk out and ignore her crying. I don't agree with "crying it out" and I certainly wouldn't start testing it out with someone else's kid.

The thing that's tough is that she doesn't really act excited, irritated, agitated, or upset in any way. She's totally compliant with getting ready for bed, putting on pajamas, picking out stories, and drinking her milk (though she has been fighting toothbrushing but from what the moms say, she's like that for them, too). Going to sleep has always been a problem for her (she insists she needs mommy to fall asleep, and they haven't been terribly consistant with deciding a plan of action for this) and the music may help - I'll have to give that a try next time.

I think, though, what I really need to do is talk with the moms about it because the solution really needs to come from them.
