My son is 8.5 and 133cm. I know I CAN move to a backless booster from a high back. But I just can't seem to commit to a choice.
We are using a joie bold and he does still fit in it comfortably but my new car means the seat belt is difficult to fasten as the isofix points are causing the seat to push on the seat belt clip.
Do I just give it up at this point? I would keep him on a booster, but a backless one.
When did you give up the high back booster?
