Hi Kerrie,
First of all, it sounds like you've so much already and good job for that! Being an involved mom is so much better than an intrusive, bossy mom in the classroom.
What a little love your child is. I bet you're so proud of her for handling all this so well with this little girl. I would be. I think her acting out is good that she feels safe with you and can share - better she vent at home with you all in the confines of her home where she knows she is loved and adored. Here are some things I would watch for as she struggles with this until the end of the year: her sleep habits and patterns - is she sleeping soundly and awaking with joy and ready to go to school? picking at her skin like around her nails, biting her nails, pulling at her hair, bowel movements, seat work in school, her grades and her teachers overall view. You were wise to get her teacher involved.
And that parent who said, the annoying stalker child has every right to the same education as your child is RIGHT. Gosh that stinks doesn't it? And don't you wish we could just take a pill and make all the bad things go away... I do. But, life isn't like that and your child has 2 parents who love her and are dealing with this head on. She is lucky! I would suggest showing your daughter how to set boundaries with this little friend. And then practice saying and acting it out with her; that will give her more confidence. And only you and your family know what is appropriate. If you are sick of all this and want to take a break from the entire relationship then do it. And just formulate a sentence for your daughter to repeat. "we're being separated from us playing until April 1 and I can't talk to you until then." Or you could suggest a recess playtime for once a week. And your daughter would tell the little girl "I only play with you on Fridays." I would absolutely keep the teacher involved with a note or phone call to squash any confusion or miscommunication. And then if the little girl persists or argues with your daughter she should then go promptly to the teacher or recess teacher and explain that the little girl is harrassing her (big word but, she can learn how to say it) and would they please help her.
I think the best thing you've done here is create a home where she feels safe and loved with you... continue to keep up the good work.
"Sometimes life is about learning how to deal with difficult people and it doesn't go away when you grow up. Some times it gets worse. You're learning lots of things in school this year and not just how to read but, how to be a good friend and I'm so proud of you"
take care Kerrie,
C.
