Crayons and drawing? What age?

[JordieC]

Just wondering what age your child started being interested in drawing with crayons? I know you can start from about 12 months (which we did). I only bring them out every few days (if that) but DD doesn't really want to draw. She's made a few marks but her fav thing is to put them straight in her mouth.

So when did your bubs show real interest in making marks on the paper (or walls! - ha ha)? I noticed in the blue health book that it is one of the items on the 18month check up.
