Why does she do this??? Grrr...sleep related

So DD seems to have gotten into a routine of sleeping well for three or four days and then the night that I have to work (I work in a library and have to work one night) she decides she doesn't want to go to sleep until almost 11PM. I fear what is going to happen on Monday, when my grad class starts back.

Do I just accept that she will be up later on nights when I am out of the house?

Grrrr....

I would try to incorporate DH into her bedtime routine as much as possible so she is used to him always being there.

We have a very firm routine of Goodnight Moon, a bedtime song, turning on the mobile etc. He usually goes down w/o problems. Once in a while he will cry for a minute then settle down.

Does she have a toy like the Aquarium thing in her crib? Good luck
