Hi,
I brought my son a new car seat a few months ago which is a Group 1 and Group 2 seat. The harness barely fits around him anymore so wondering if it would be ok to use it with an adult seat belt now? In the instructions it doesnt give a height but says to use from 33lb but the Group 1 bit says up to 39lb?
He is 3 in a couple of weeks, weighs 33lb and is 94cm tall.
TIA X
