Does your toddler like to do messy things like play in the mud, fingerpaint, play with their food etc?
I was thinking about signing baby boy up for a messy art class, then I remembered last time we fingerpainted he dipped one finger carefully in, wiped it off after each stroke, and kept asking for a paint brush. He doesn't like his hands to get messy. On the other hand, maybe it will be good for him! The class also does playdough, bubbles, flubber etc.
