This is the first winter that I've walked my 2 older kids to school and school bus stop (2 different schools) every day (changed half day kindergarten time so we could walk it). At 3 year old speed everything takes 3x longer. (stopping to poke hedges, splash in puddles, intrude on neighbours property, check out snow, talk about dog in window). I've figured out between 4 walks a day, we spend at least 2 hours a day outside. We dress appropriately and we haven't had a problem. Actually, usually by this time of winter I've been sick a few times. I'm probably cursing myself here, but I haven't had been sick yet. I enjoy watching the kids reactions to the change of seasons. It doesn't matter how many times they see rain or snow, they love it. They like the sun coming out. They're interested in all of the squirrels and chipmunks and birds that they see. And what is wrong with smelling like the outdoors?
