Mr8 knows that the law says he doesn't need a booster and he is getting increasingly bolshy about using it.
He is too tall for any with sides etc so he is on one that is just a seat.
What age did your big kid stop using their booster? I was planning on using it until he was 12 but I'm not up for years of tanties and power struggles.
Is the no booster issue a phase or will it be ongoing?
