K.S.
I had my girls out younger than that in snow...it's lots of fun and who wants to be stuck inside all winter! I like the previous ideas of snow pants or even layering because it is true at that age they won't be out very long. And you will definitely get use out of whatever you get with #2 because next winter you'll be out more with the older one. There are little plastic sleds you can by that are seat shaped with a buckle, those are fun for that age! I would also get snow stuff for you, cause with a little one I know I am down in the snow with them helping to make it fun! I was pregnant last winter and was able to wear snow pants lower beneath my belly and my winter coat fit around my belly almost the whole winter. (baby was born in May)
