Hi tiger - yes, personally I'm thinking maybe making friends at start of secondary is quite a good thing to be a bit pro-active about. But also true that we can't do it all for them and they're going to need time to form their own friendships. But a bit of effort from both them and us in the early weeks may be easier and more effective than trying to fix things if they feel a bit left out later on ? Hopefully other parents will be doing the same and a bit of enthusiastic appreciation of their efforts goes a long way too I find. Always surprising when some children don't go to parties or sleepovers they've been invited to. Go to everything in the first term !
I'm sure it will be fine and they'll all have some new good friends soon.
