hi was just wondering about the new car seat law, that everyone under 11 or 12 should be in a car seat. the only thing is some of my older kids weigh too much for the boosters but are only 8yo. have just weighed the 2 i have this afternnon and one is 30kgs which is ok and she has a maxi cosi rodi but the other one is 46kgs and the top weight i have found for a booster is 36kgs.what do i do then? do you not use it as car seats should be bought by weight, but what if i get stopped by the police? help!!
