So we're in the middle of a polar vortex of some sort in PA (although, thankfully, no snow yet) and I'm finding myself totally unprepared to take the baby out in cold weather.

I'm interested in getting him something like this:

I am particularly interested in this suit because it's zippered and has feet (he will immediately remove any shoes/socks/slippers that I put on him) but he will definitely not fit in a 9 month size. I'm looking for at least 12 months...but I'm guessing I might not find a 12-month suit with feet.

Anyone have something like this with feet that comes in a larger size? I'm checking out consignment stores today.
