My wife and I are looking for someone who can provide after school care for our 7 year old son. We live in Lions Bay (public transit runs on an hourly basis) where he attends school. We need someone who can meet him at the end of the school day, walk or drive to our home (a bit more than 1 km uphill), and \"supervise\" him for 2 to 3 hours. He loves to play both inside and outside and can keep himself entertained for hours at a time. No videos/movies/electronics are allowed and he\'s fine with this. We will also need someone to look after both of our kids (5 y.o. and 7 y.o.) 2 or 3 days/week this summer. A significant amount of the time may be spent at the village beach as they enjoy their time there.
