DD is 3years, 7months old. She's 20kg and the height of a 5yo (maybe taller, she's in size 6 clothes)
I've been looking for a new car seat for her, but just realised once she's 4 years old we can move to a lap sash.
Given her size & age, would you just jump the gun & get a booster? Or invest in another 5 point harness?
I know most of then convert, thing is I just won a booster on ebay, not realising it didn't have a 5 point harness :-/ what would you do?
