DDs are nearly 8 and 6.
Last week DD2 went home with a friend for tea & play, that evening she told me in the car to her friend's house she wasn't wearing a seat belt, because there wasn't one for her! (her friend was in the front on a booster and seat belt), the mum also had her toddler in a car seat and another girl who she drops home in the back with a seat belt. DD2 was in the middle of the back seat with nothing. I was furious.
Then tonight DD1 was supposed to be going home with a friend and i happened to ask this morning if she had enough boosters and the mum said "oh no we don't use them anymore". AIBU?! DD1 is quite tall but surely they should still be in boosters. Mine are both still in high back boosters in my car and i would never give a child a lift without at least a booster never mind a seat belt.
