I was wondering from what age you found your ds or dd starting to draw, paint or otherwise make marks? My wee one is 12mnths and I keep on wanting to give him pencils, crayons, brushes, big fat toxic marker pens, whatever. Partly cos I love children's drawings, although I also confess that this is a little bit connected to my work interests as well. So far he just trys to eat them, ooops with the big fat marker toxic pens.
One thing I have read about is how attempts to push around and make shapes in spilt liquids (or urp) or sand or dirt should be valued as the first mark makings.
