Thank you for all of the kind comments. I have been talking to dd and making sure she is good for tomorrow, she seems happier now, and I have reminded her that her friends will be excited to see her regardless of the sleepover.
I don't feel I am overreacting, but I can't just simply ignore my dd's feelings (and upset) about this, and other girls are always having play dates etc and she never bats an eyelid, so dd does not have form for being overly upset about every day girl stuff which is why this is quite out of character.
RafikiIsTheBest my dd and another girl have been great friends since they were 5. They play one to one and with groups of girls and have never been exclusive, but they do have a strong bond. The new girl arrived around 7 months ago and is very sweet, and we have all made her (and her family) very welcome. My dd likes her a lot. All good to now, and lots of sleepovers and play dates and outings with all three, and sometimes four girls. Up to now they have all done things together, although sometimes we all have one to one sleepovers. No problem.
Last month I noticed that the new girl's mother was fawning a lot over the other mother, I would go as far as to say it is quite nauseating, but I still really liked her, she is good fun and a nice person.
When we do things with the dds we tend to do it as a group and include them all, which is why I was so surprised that she would arrange a sleepover for just two of them the day before the girls outing without mentioning it. In the past we would have made the sleepover for all of them, naturally not wanting to leave one out. They all love sleepovers, but for many reasons we can't do them very much, so they are a rare treat which is why my dd was so upset.
It was not an accident and the other mother doesn't need childcare, it is a Sunday night and we are all at home.
I don't know what the term ' Helened' means? Please tell me. For the record I am not the kind of parent that would ever do this, I always think through the dynamics and so does she....usually.
