So I'm asking for advice on this one as a) I don't know if this is normal behaviour and b) I'd like some opinions on how to tackle it to prevent me going crazy.
I have one dd14. We holiday once a year in the same place and she has made a general group of holiday friends who go the same time. They and us (parents) aren't in contact any other time than on hols. One other family who have a younger sibling (currently 7) demand the teenager keep the younger sibling with them at all times. This causes so many issues for the group of friends. They are a group of 8 (all 14 or 15). They want to do certain activities that teenagers do and also, because there is two lots of 4 they fit nicely in parents cars if they need a ride to an activity etc. However the 7 Yr old HAS to go everywhere....and I mean everywhere (bar the shower). If I offer to take some of the group out I get "well aren't you taking X'......DD also gets left with X (as do the other teens) if their sibling needs to go toilet, fetch a drink etc. It's putting alot of pressure on the teens to be responsible, massively restricting what they can do but also making me a bit peeved that their parents go off doing as they please all day while their teen and friends are childcare. I dont think I can explain enough how much they have to take him with them....quite literally everywhere and every second. I think it would be so much better for him going to the kids club to socialise with kids his own age as this is what they say "well he doesn't have any other friends".
Is this normal for a family with two or more children please?
