I'm going to give them the benefit of one warning.
We haven't really been doing any art up until now because of the ages I"ve been dealing with--most of them are under 2 and are have NOT been interested in things like art. And have a tendency to eat everything. Even crayons. And markers. I also haven't had a useful sort of table for them to do things on--now I have one of those HUGE 8-seater picnic tables from Little Tikes. So, I'm finally getting on the ball and feeling like I can toss art into our days now.
