Hi, really not sure what to do about this. Will try to keep it brief.
We moved back to Sydney 7 months ago and it took DD1 and DD2 a few months to settle. One thing that helped was our friendly neighbours over the road who made them both feel very welcome - they have lots of animals and a DD who is the same age as my eldest, but in the year below at school. Anyway, DD1(10) is a confident, chatty girl who has quickly made lots of friends and so gets quite a few invites to parties. DD2(8) is very quiet and has made 3 or 4 good friends, and that is it. That's fine, its the way she is.
I have just received party invite from my neighbour for her daughter's birthday party saying 'sorry for the short notice but hope your girls can make it', sent as a group email. I said 'yes they are free' and checked that she meant the invite for both girls. Turns out only DD1 is invited (I should say here that DD1 and neighbour's daughter were friends before we moved away 5 years ago).
The trouble is that DD2 thinks this girl is her friend as well - before Xmas the 3 of them played together all the time. Over Xmas, and since, both DD1 and neighbour's daughter appear to have largely lost interest in each other and spend hardly any time together. DD2 would like to go over to play but won't go without her big sister.
DD2 is quite sensitive and I can't think how to explain why her 'friend' hasn't invited her without hurting her feelings. And while I know she needs to learn hard lessons, she has learnt plenty of those in the last few months having moved away from friends and family. She is only just starting to feel at home here - and our neighbours were a key part of that. I am genuinely worried that this could cause a deeper upset than just 'missing out on a party' - she doesn't seem to mind that she hardly ever gets invited to parties.
AIBU to consider not telling either daughter about the party (and hoping my neighbour understands)?
