The weather is getting colder and I want to continue going for walks outside with my baby in the Beco. I also use the Beco for convenience when going grocery shopping/errands etc. so I often am outside with LO in the Beco for brief periods to walk across parking lots to my car etc.

LO was born last winter and I didn't really wear him outside then. It was just as easy to put him the car seat and stroller and cover him with blankets so he was warm.

My question is: how do you keep your baby covered and warm in the Beco? I have a good hat for him, and I will get him mittens... but I am hesitant to get one of those bulky/puffy baby winter coats as I imagine it will make wearing him more difficult. Also it will make strapping him in the car seat difficult when I drive him around (and when he is in the warm car and I am driving I can just give him a blanket anyway like last winter).

What do you do/use?
