If this is hurting you then the kids can feel it to therefore they are getting hurt to, find a better fit. There may be a simple explination to this. example again I say this alot but it is important to know My son is allergic to eggs, he was in a wee three program last year and I work during those hours so my sitter would take him, I noticed the few time I was actually able to take him all of the kids were inviting all the other kids to b-day parties, but my DS was NEVER invited to one. I could not figure out why, it hurt why single out my baby he is social and all the kids seem to enjoy his company. Then it dawned on me EGGS. They do not want to take on the responability of something happening to him in their home, duh right. So simple and trust me I was P.O'd and hurt. now not so much. He knew nothing about it. Plus most of the class was girls ewwwh a boy right kewties.
so I bet it is something simple, but you 2 need to be someware you will not feel like this. This year we are invited and I make the cake, the world is good again.
Good luck. and look in the mirror it is not you!!! It is them!!!
