Carseat blanket - Morcck replacement

[worriedaboutrash]

Hi everyone, I’m searching for a car seat blanket for our newborn. I need it primarily for doing the school run with the older children - something to wrap around baby so she can continue to nap instead of being disturbed to put on a coat for a 10 minute drop-off.

With our first two, I used a Morrck blanket as at the time it was the only one that had been fully tested and was recommended as a safe option. Although there are loads of options on the market now, I only want to buy one that is fully safe and crash-tested, etc.
Any recommendations instead of a Morrck?
Thank you!

My understanding is that a cellular blanket is safest for a newborn to prevent overheating - these are widely available. As far as I’m aware, none of the wrap type blankets or anything that goes underneath baby, has buckle holes etc are safe.

I would just use cellular blanket and/or put their coat on back to front over the straps.

I would also just tuck a cellular blanket around the baby. Hat on head when you get out of the car (if needed).

Thank you :)
