I don't remember exactly... They were both early toddlers, I think, but Violet didn't really care that much about it initially and Leo doesn't currently care about it. I know that Violet enjoyed exploring art materials around age 2, but then became destructive with them and also stopped caring about them. Around July of this past year, Violet started creating representational drawings at about 3 years 8 months. She still doesn't draw much though but I know she practices writing her name at preschool.
