I remember the paint with water books when I was little. I LOVED them! What I love even better is today's reusable version, Water WOW! by Giddy-Up. H has the Giddy-up Princess Water Wow Book Activity Book
and the Dora Water Wow Doodle Book (Dora the Explorer-Nickelodeon)
H is kind of heavy handed with the 'brush' the first time we tried it which resulted in the coating on the pages getting scratched alittle bit. Instead we use a sponge brush now which works beautifully.
H loves 'painting' each page and seeing what's hidden. Each page has activities like counting the fish or find 3 circles which makes it educational as well. The only down side is that each book only has like 5 pages. Still H loves them and I love that their reusable!!
