OK - so this is quite new for me, but it does say get stuck in on the "getting started" bit!
My son aged 10 has a good friend who we often have to play/sleep over; they are both in Y6 at school. My son is an only child, his friend is one of 7. So although we have him to ours more than our son goes to them , that makes sense, if you see what I mean.
My partner and I are friendly with my son's friend's parents to the extent they came to bbqs we had in the summer, but not really close friends.
Anyway - son's friend is 11 next weekend and is having a sleepover for 5 friends. My son is not invited. Considering they play together at school all the time, and have these regular out of school/weekend meet ups, and considering I fairly regularly (last time Friday after school) have friend when his mum is in a fix/tied up with older/younger child, I am a bit put out. Am I being unreasonable?
