@randyt68 Fellow Aussie here. I usually take LO’s jumper off and put an oversized jumper on over the carrier if my arms are cold. I can do it up if it’s windy for LO. If I’m home and it’s cold I’ll wrap a blanket around LO and tuck it in to the straps if I feel they’re cold still but I don’t...
@conoro I don’t know European standards or law, but in my country if the seat has been in a crash (and hard enough airbags have deployed) that seat is no longer safe for use. Cut the straps, damage the shell, take it to the dump and claim insurance.
