I'll try and put it all here as don't want to drip feed.
My friend has 2 DC's. 1 is 11 months older than DS but the same school year and the other 6 months younger so closer in age. They attended the same day nursery, go to different schools, but same community after school club. (Surestart/minibus)
Due to her DC's birthdays being 3 months apart she does a joint birthday on the middle month - her DC's invite their friends and DS gets invited as an extra guest so they can invite the same number iyswim?
This year she said she had booked the party, said her DC's were inviting X number each and so she was expecting there would be Y number. No mention of DS. I spoke to DS and said it seemed he wouldn't be invited and he had to accept this as they would invite their schoolfriends. He was fine with this.
When in town one day she popped into the shop to get invites and her DC2 said to DS he wasn't going because they both wanted to invite the same number of friends. DS said OK. The DC2 kept going on and DS said he wasn't bothered about not going.
Roll on now when I'm organising DS birthday treat. Money is tight, his birthday is school holidays, so I'm doing a game of bowling and Maccy D's for him and 5 friends. Party treat is only for 1.5 hours and is no thrills. It is to be next month before they break up as historically people say they'll come during school holidays and then can't/ don't.
DS decided he wanted to invite 2 school friends, 1 boy from our road and 2 girls from after school club, of which one is friends DC1.
Friend RSVP'd that her DC1 couldn't go. As yet DS has not decided who to invite instead. He is pragmatic and overthinks things is thinking it should be a girl and someone else from club so the other girl has a friend there!
So today we were out at a local park and see this girl. She introduces me to her father who was there and we talk about the party. He didn't know me so was nice to meet him. I do not know the mum either mind!
So whilst we all sat having a drink the girl says to DS ' DC1 is really upset her mum won't let her go to the party'. DS says he knows she can't go and he's sad too. The girl then says she can go but her mum won't let her without her sibling as all 3 DC's are friends. Girl shows a text (yes I know 8yos with mobiles!) from DC1 that says as much and that shes really cross her mum said she cannot go as her sister threw a tantrum over it.
I did not get involved with the list DS wrote, he made the decision himself. I know he finds the DC2 hard work, plus she's in Infants and them juniors. I do wonder if he did have some ind of payback in mind for her going on about how he wasn't invited to theirs (DC1 didn't mention it just didn't give an invite iyswim?). I do not think my DS has the social skills it in him to be manipulative and cruel this way though.
I rang my friend and asked her about it. She basically said it was unfair to exclude 1.
So AIBU to have let DS invite the 1 sibling?
