I hate winter! DS has outgrown his infant seat and I've moved him to a RF'ing convertible. However, it is COLD (I'm in SK) and I have to take my DD to school and pick her up every day. I hate having to take DS out of his seat to carry him in when it is so cold (-22C with a -35 windchill today). Poor little guy was gasping in the cold even with a blanket over his face. So, I am considering buying a higher weight bucket so that on the really cold days I can just leave him in it for our quick in and outs. He's about 20lbs and 29 inches tall with a long torso and short legs. Am I crazy to consider buying a new infant seat at his age? If I do go that route are there any good sales on (Canadian) atm?
