DH and I live in sunny SoCal, but ILs live in snowy Wisconsin. We are traveling there at the end of March (LO will be 12 weeks). We visit every Christmas too.
It comes in two sizes, infant and toddler. If we are using it at 12 weeks, and not again until probably 10 or 11 months, would you get the infant size or the toddler size? Does anyone use this cover or have recommendations about winterizing baby?
Thanks for the advice. I thought I moved to California to avoid this kind of stuff....

Re: Stroller winter blanket
We have this: https://www.amazon.com/JJ-Cole-Seat-Cover-Khaki/dp/B003ZUXQXU/ref=sr_1_3?s=baby-products&ie=UTF8&qid=1393783789&sr=1-3&keywords=jj+cole+stroller+cover which just comes in one size and then also use a blanket in the seat with him. This is probably something you're all over, but don't forget a warm hat that covers the ears
I'm also incredibly jealous that you live in a place where you don't have to worry about that. Every time we leave the house I'm thinking "How frigid is it today? Is it Aden blanket cold or super fuzzy blanket cold?" I'm not convinced it'll ever be warm enough to take the damn cover off the car seat. :-<
