Can baby wear a jumper/cardigan in their car seat?

Thin cardigans and jumpers only, nothing thick. Stops the harness from working correctly. Can put a blanket over the car seat loosely once they’re all strapped in x

A thin cardi is more than enough! Pop a blanket over them once they're all strapped in! X

As mentioned, a thin cardigan. But nothing with a hood

You can get special car seat blankets too that go under them then wrap over the straps if you've got a kicker who keeps pushing it off! Means the straps are still nice and snug but little ones warm

these are really not recommended, you shouldn’t add anything to the car seat that it didn’t come with.

these are advised against! X

Our midwife suggested them and the one we've gone with has been crash tested. Cost a bit more but worth the extra for the testing
