Just interested really.
Dd1 is 2cm shy of not needing a booster cushion at all (133cms) and will be 9yo in less than a fortnight. She is delighted at the prospect of not needing a booster, but she still seems v young to me to not have one. How old was your dc when they no longer used a booster?
Dd2 will be 6 in 2 months time and wants to use dd1s booster cushion rather than her Maxi Cosy rodi, but again, I think she is too young. At what age did you switch your LO to a normal booster cushion?
If you haven't yet done either, what do you think you'll do when the time comes?
