S.D.
Oh my goodnes, that must be so hard! I have 2 two 1/2 year olds. One girl and one boy. My daughter is just like yours in the sense she has never had a problem and the out of nowhere she is not wanting to go to bed. It is hard to deal with because, I don't know about you, but I get really frustrated and I don't like to get that way with her. My daughter has done it a few times in the past 6 months (life changes and not). My son just goes to bed ALL THE TIME! :) I just kept doing what I was doing and there was cryingn sometimes and fits and then just pushing the envelope. She fought it and pushed her limit, but I still said it was time to go to bed. Yep, it takes a long time in the beginning, but eventually she will realize it is not worth it. She eventually wore down. I think even though there are no changes in family life and schedules, there might have been something in her mind or experience. You just never know. Dreams, things during the day that scared her, stories she might have heard that you didn't know she heard and interpreted it differently. That is the most amazing thing to me! I hope it gets better and I am sorry it is so hard. You are most tired by that time at night too!
