DS is a very large almost 2 year old, he weighs about 20kg and is very tall. He has always been big, was 10lb9 at birth and has just continued to be massive 😂 he isn't overweight, just large.
We have the joie everystage fx carseat currently which I love but is very heavy and I usually leave it in his dads car (we are separated) as I don't drive so only need a carseat occasionally if going out with friends etc.
The straps for the everystage say maximum weight limit is 18kg, which would be fine if DS wasn't so big for his age. We have switched to the seatbelt as I am worried that the straps won't hold up in a crash if he exceeds the weight limit. I don't like this but feel it may be the safest option?
Now I'm looking to get a carseat to keep at mine, for when I have unexpected trips out etc but can only find group 2/3 high back boosters that cater to his weight/height. I know the general advice is rear facing etc until 4 but how can I do this when I can't find a carseat that will work safely with my son?
Would i be unreasonable to use a high back booster? If it is a bad idea could anyone suggest a carseat that will work for a 20kg almost 2 year old?
Thanks
