I might be biased given that my 2 year old didn't take to this activity very easily... it is clearly meant for older toddlers with more developped concentration and motor skills... I didn't find this product worked very easily. It took more water than expected to get the paint to run enough to actually transfer well from the brush to the image. Even while playing with it, myself, I found it somewhat more challenging that I would like.
Direct "paint with water" books & pads are a better choice.
