We like to go on walks at night a lot (it's pretty nice when you leave with awake kids and come home with sleeping angels). Here's a few pictures from the other night when we actually let the kids walk (as opposed to smoothering them with 15 blankets in the jogging stroller - bless that thing!). They endured the cold pretty well.
Dad had to get in on the action, too...
And here's a cute picture from a year ago, so you can get the visual on what parental bliss looks like (yep, that's a puppy sleeping with Serenity, see it works on animals, too!).
