Keep them moving...

Well, of course, it would be even better to get kiddos out to run, jump and climb... But when the temperature is -15c, most of them decide to play indoors. My son tried to get his friends our for a couple of times, without succes. Hence we decided to play indoors instead.
It's actually surprising how well he has been using his new fitmeter (part of wii-system) and trying to achieve the goals every day. He is proudly uploading his steps into the system every night. So maybe all these videogames are not that passivating...
