Our daughter, who turned three a couple of months ago is ignoring our requests to do things or gets really upset when we ask her to go to the bathroom or other small things. She also has a hard time going to sleep at night and usually stays up for a couple of hours. We have tried time out, sticker charts, spanking, talking with her and probably a few other things I am forgetting. She is very strong willed and determined to do things on her own. Any suggestions?
