Arrrghhh....sleep problems

Wee one has started being tantrumy about sleep and also a few other activities, but sleep is the one that concerns me. Crying, throwing stuff out of her crib...saying "NO" when asked to come take a nap, go to bed, take a bath (activity usually right before story time and bedtime). I am not sure why this is happening now exactly. Of course our household has been different since my parents have been living with us for the last 2 weeks since my surgery and I have not been able to do my usual mom things very much. They say we spoil her some and of course, they do too, being grandparents. But in about 1-2 weeks, things should be returning to normal soon. Maybe it will change then, but maybe not. It is the time of terrible twos.
