I would hold off on a high back booster still. I have a 99% percentiles for height in rear facing still, she just crosses her legs. If she has to be turned I would still keep her in a harnessed seat for now. Xx
@Mel s she's been front facing since a year anyway
My son is 3.5 and has the same seat as Anna has mentioned above. He has been forward facing since 18 months but outgrew his seat so just brought that one 😊
@Anna I’m looking at getting this one in the next few months
I'd let her complain and keep her rear facing until she physically can't fit. There are 6 year olds still rear facing so it's definitely doable.
