DS is 18mo and we need to get him a new car seat. I was advised to get a 'convertable booster' (eg. SNS maxi rider) which would suit him right up to 26kg. But I did some research and apparently it is a horrible seat to use in booster mode. So I'm thinking of just getting another convertable baby seat (birth-18kg). My question is, do they really last until the child is 4 years old? Can you go straight from a convertable baby seat to a booster (4-8 years)?
DS is currently in a SNS convertable baby seat and I just can't see it fitting him at 4 years old. Is it possible that he may outgrow it and require a 'convertable booster' to fill the gap between baby seat and booster?
