I have noticed a huge change in children when they go to school for the first time. I have already started to notice bad behaviour from my daughter just by going to pre-school. My opinion of it is this: At school the teacher cannot be overly strict, she cannot spank, doesn't yell and usually won't hand out time outs as often as I would. They have approx. 20 kids who need their attention therefore there are some that get away with the bad behaviour that we have been trying to not allow. Our children are smart - they see the other children behaving that way and see that they get away with it and then they also try it. Then there is the jealousy issue in there as well. She knows what goes on when she is away and wishes she could get more attention from you.

My advice is to step up your discipline. Stick to one thing (the one thing your child hates the most). I would not send her upstairs to watch TV, that sounds more like a reward to me. Next time she doesn't want to be around the other kids she will just act out in hopes that she is sent upstairs to watch TV. You will also need to do special things for your child to make her realize she is still your No. 1. For me when my daughter comes home from pre-school she gets 100% of my attention for 5 minutes. She sits on my lap and tells me all about her morning before she can go play with the others. I make a big deal about her crafts she does at school and we plan things we are going to do together when she is home in the evening after daycare.

I hope that helps.
