She took two of my DC in her car this week. Drove them for an hour and a half each way to an event.
So far, so good. Until I discover that she had 5 kids in the car with her as she had miscounted. One of mine is still small enough to need a booster and was sharing a seatbelt with another child and had no booster.
I genuinely don't know if I should say something - they are moving soon and it is unlikely to happen again but I worry about her children as well. If she had asked I would have happily have lent her my 7 seater.
Would I be unreasonable to mention that I would have lent her my car? And that it is bloody dangerous not to restrain children properly in the car?
