No winter coats in car seats....

So tell me what you do? I’m a FTM and my baby is a small ten month old in a rear facing convertible evenflo.

So I put her in the coat, take her out, put her in the seat, take her out, put coat back on in the cold? I’m having an existential breakdown over this basically.

What’s your process? How do I keep her warm as the winter gets colder and colder here in the north!

Help!
