So this winter is only my second winter living here and my first with a baby. I need something to keep my 3 month old warm in her B-ready stroller, but I'm not sure which product to get.

Price is definitely a factor, but I need it to be warm and last for a long time. Can I get by with an "toddler" size even though she's an infant (I heard the JJ cole brand runs small).

Should I get the urban? The arctic? Right now on Mat leave, I rarely drive and do most everything walking with LO in the stroller. On weekends, we rarely drive.

Also, our car is in an unheated garage on the lower floor of our building. Do I need something for her carseat, too or will I just carry her down in a blanket or something and pop her into the carseat without anything over it until the car heats up (I do commute by car further out into the suburbs, and will probably be taking my LO to daycare out there starting in January.

I used to live in Texas, so cold weather is all new to me.
