@Lauryn should I look at getting a new one? If so which is a good one?
Join the car seat safety group on Facebook, this one isnt recommended. We have got this one x https://www.simplysafecarseats.co.uk/products/avionaut-cosmo-2-0-smart?variant=48972885655880
I have a britax baby safe core and it’s fabulous! My girl was 6lb 11oz and she fit beautifully. You can get adaptors which fit most pushchairs too
It’s not that they aren’t safe - most infant carriers are due to the curved shape - it’s more they aren’t very supportive and especially if you have a small baby they can be very chin to chest which is something you want to avoid
