We have a group of friends of 6 couples plus their assorted children. 5 of us have older kids (13-20ish) and 1 of the couples (couple A) have very young children (3 and 8 months)
Normally when we all get together we do stuff where the children can come too (although normally the older ones choose not to) and we'll meet up at each other's houses for a takeaway, or we'll go for dinner at a family friendly pub or restaurant.
Sometimes though, we all want to do stuff without the kids - most of us have children old enough to stay home now so it's nice to be able to get out and socialise with friends. Whenever something like this comes us though, couple A kick up a huge stink - that we're unsupportive, that we're excluding them and leaving them out.
A few weeks ago it was my daughter's 16 birthday and she wanted to go to Thorpe Park. It came up in conversation with the other families who all said they'd love to come too. The more tickets you book the cheaper it gets so I said let me know and I'd book the tickets. A few days later couple A contacted me to ask if we could go to Lego Land instead as Thorpe Park wasn't really suitable for their kids. I said DD had her heart set on Thorpe Park so we'd be sticking with our original plans. The other couples said they'd prefer to stick with Thorpe Park too as they all wanted the big rides, but we suggested we could all do Legoland next summer
Huge fall out ensued, we were all accused of being unsupportive, that we'd forgotten what having young kids was like and we were excluding them.
It mostly blew over and we've got together a couple of times and all was OK
Anyway, a cheesy nightclub has opened up in our local town and we all fancied a night out. Everyone was invited, but again couple A have got upset.
I like them, they're both lovely and their kids are great, but my kids are now old enough to leave to their own devices for an evening and I don't always want to do stuff with their young children.
We mostly do stuff that includes them, so it is really that unreasonable to expect them to suck it up sometimes when we want to do stuff that isn't suitable for their kids - or, they could always get a baby sitter!
