Does anyone else get nervous when their kids go sledding? My kids love it of course, but I get so nervous. We stick to small hills and stay clear of trees (like wayyyy clear) but I'm still a nervous wreck. They're getting older (5 and 8) and want to go down bigger hills now. I grew up in the south so maybe that's why it scares me because I'm not used to it. Now we live in the north and it's a part of life here and I see all the other kids and parents whizzing by us. Does anyone else feel this way or just me? Do your kids wear helmets when they go sledding?
