Having a Hard Time with 1St Grade

First I would see if there are any big changes effecting her life right now, and see if she is stressed about them. Kids act out and things like this in order to cope with bigger issues they can't deal with on their own.

Maybe her teacher gets angry at some of the kids. My daughter went through this and she was sick because of worry and stress over the other children who were being yelled at.

As the other response suggested, you really need to get into the classroom and see what is going on. The problem could be anything from another student to the teacher to struggling with the work or paying attention. At your child's age they do not openly admit problems they are having because they are afraid to face it. Talk frequently with your child and find time to visit the classroom- and maybe the playground at recess to observe your child.

I had a daughter who had this same problem in 2nd grade. She actually was in a full time Kindergarten and we moved here and she loved school. I did not recognize the signs and I tried my best to help at home. I had a medically challenging baby born the March before this, so I was rarely around as I spent most of my time and energy on the baby. I counted her problems on the instability of home life. It wasn't until late in the year (and not worth the effort) before (in talking with a friend that worked in the school) I realized that the teacher and some of the kids in the class even were adding to the problem. I know I couldn't do anything at that point, but I made a point to make sure she was not in the same class as these bullies and made a point to get a good teacher this year.
It isn't the fault of your child nor the teacher. But we all have our own personalities and at a young age, you should not be forcing your child to get along with someone that clashes with their personality. So as those before me have suggested, observe the class and possibly talk to different aids that might come and go. The teacher and students will behave for a one time observance. So if you can't get involved, talk to other mom's and get their opinion.
Good luck

That's such a long time to be gone everyday for these littles ones. My son is loving kindergarten but keeps asking when he can stay home. I think he feels like he's missing out on fun things at home. I can't believe how well sticker charts or reward systems works with my kids! Maybe each day she comes home, you can add a sticker to a chart and at the end of the week go out for ice cream, or go to the park. I would also try to find out if there's something going on at school that is causing her stress. Good luck!!
