I’ve just bought a group 2-3 car seat (maxicosi rodifix) for my 4 year old. It says from 15kg but she’s only 13kg but height 99cm so getting a bit tall for the maxi cosi pearl. What are your thoughts? Is it safe to put her in the rodifix at 2kg below recommend weight? I’m guessing not but if it’s more about the height because of where the seat belt sits then is she safer in the rodifix?
