"I want a Christmas activity" is the catch-cry at our house at the moment, it's already wearing a little thin. Activities have included moon dough, magic sand, painting, playdough, new toys, games, etc... One of our more unusual gifts to the kids was a can of shaving cream. It has already emerged at bath time for some slippery fun - the little one was calling it "Shame" which is a cross between shaving cream and foam.
Shame with food die - Fame perhaps.
This activity got a little messier than I expected. Little one required a bath at the end. Amazingly the big Bowerbird cleaned the whole mess up while I was bathing little Bowerbird and said it was fun. A very tactile activity and a good lesson in mixing colours as well.
