My DS is 3.2 and weighs just over 18kg, he's also very tall for his age. He's currently in a BeSafe izi combi isofix, but the weight limit on this is 18kg. So I think that he should now be moved into a high backed booster seat - if that's correct?
If I've understood it correctly he would need a Group 2/3 one, that he could stay in until he no longer needs a car seat. I was wondering if these kinds of HBBs have 5 point harnesses? I read online that 18kg is a top limit for a 5 point harness on a HBB, so would that mean my DS wouldn't be able to use a harness?
I'd be very grateful if anyone could tell me if I've understood this correctly!
