My sister, brother and I all had boys within two months of each other - they are now all about to turn 13. I am very close with my sister and for the first few years, our boys played all the time. However, at some point the two other cousins started teaming up and actively excluding my child. My brother's son told me that my sisters's son had made a point of telling him to to shut out my son. When my son and my sisters son play together one on one, they get on fine. However instead of getting better as they get older in some ways it has gotten worse and my son recently said his cousin (my sister's son) hates him. My husband and I have recently made plans to go away on a long weekend biking trip, and also to do more tramping. We decided one trip would suit one cousin (to take along as a buddy) and the other trip would suit the other. On that note, I asked my sister if her son could come with us for the long weekend, and she said: "Oh, that's his birthday weekend, so he can't go." So I thought, oh well, we will invite the other cousin then. I just asked them, and he can't come either - because he is going to my sister's son's birthday party that weekend. In other words, my sister's son has invited my brother's son to his party, but my boy has not had an invite. Here we are a very close family growing up and my child is being excluded. I also just found out they spent most of the school holidays together (when I went to ask one if they wanted to stay and he was unavailable. Guess why). I find this a heartbreaking situation. They are all the same age, but my boy is not included. We recently found out my son has a disorder which makes it harder for him to pick up social cues (not ADD). He is very bright but just cut from a different cloth. I am gutted my sister allows this to happen and that my son has been blamed for being the problem, rather than efforts made to include him. I'm just so sad about it. I wondered if anyone else had experience of this among cousins. It's very hard to get away from when it's family. It has effected my desire to be at family gatherings for years, because I can't stand to see my son being excluded and then blamed for it as well. BTW my child is a lot of fun and quite lovable, he has a great set of friends at school.
