DD is only 4 and has been in school throughout lockdown as I am a key worker. There were a handful of other girls in her class so they all played together and clearly spent more time together as smaller pool of children there. I know all the mums, we're not close but nice and chat if we happen to be walking home the same way.
Today on the way home one of the girls asks if we are going to Lucy's party (not her real name). I said we are not invited but have a lovely time.
My DD started to cry and has been very upset all evening. She said she plays with Lucy everyday and Lucy said my DD could go to her party.
I have never been in this situation before. AIBU to be really sad for my DD. She was the only girl from the keyworker group not invited. Should I say anything to the mum? Could it be an oversight. The other parents have recently got closer but surely that shouldn't mean you leave out one child.
