Hoping someone has solved a similar problem! Basically DS is 6.2yo and he is exceptionally tall considering his skinny little body. He is 137cm, so just over the legal limit for car seats but he definitely needs some sort of carseat still. He has outgrown his Maxi Cosi Rodi highback booster seat (the back is on the highest setting and can't go taller).
I don't know if I should just take the back off the Maxi Cosi Rodi and have him on the booster part of it only (not sure if safe for such a young child). I don't know if I could take off just the head part, leaving the majority of the sides intact (?) - the head hugger thing is on his shoulders so he isn't comfortable in the seat, not sure if the seat can even do this.
Or I don't know if the maxi cosi rodi comes up small and whether I can get a bigger high back booster?
Any help greatly appreciated!
