S.B.
I have been through this exactly. My daugther is 3, and she will go down well for couple weeks, then test me for one, then do good for another couple weeks. The rules taht i have are: you get everything befroe i leave the room. if she gets out of bed, i put her guard rail up and it may take an hour but she will fall asleep. just dont give in, they will still love you in the morning. Lately i have the rule that if she is good and quiet, i will come in every few minutes to give her another kiss. That works well, that rewards her for being quiet. Tell her that you are going to sleep now too and have to go. In the am, she used to like to climb in bed with me, but then it kept getting earlier and earlier. THen i would get up and go into the living room with her and put on the tv and i would sleep longer. it was hard, but it would keep her out of my bed. It killed me because i wanted her there too, but it is best that she doesn't. She was good with naptimes until about 3 years old, at daycare they have to lie down, so at home i make her too but it is a struggle. But mine will give up when i am adimant (sp?). I hope this helps.
