Well, cute, but he kinda looks like a pile of laundry. He should have boots on too, but good for you to keep his head covered, you lose a lot of heat through your head!! Really though, how cold could it have been?
About 2 hours south of here was the coldest place on earth yesterday… -40. It's been colder than that around here before but Siberia was only -5C (23F) yesterday. By contrast, the warmest place on the planet yesterday was some place in Venezuala... +52C (125F). That's , actually, just as bad as far as comfortable temperatures go!
On super cold days, I remove the hood that comes with the suit and instead, I put a snood on her. In my experience, it stays on her head most of the time because the back of the snood is loose/open (not connected to anything) so it has room for movement like when she wiggles or shakes her head, and it stays in place :)
