Before getting your baby set up, this activity requires a little prep work. Get your white piece of paper and cut it into the shape of a fish. I just did an easy design and made a triangle tail and circle top. I cut out a little mouth, too. I used my black sharpie to draw an eye on each side of the paper, and then put it into a large ziplock bag with orange washable paint.
I gave the bag to Layla and let her explore it first. She of course wanted to eat it, so with my hand over hers, I helped her spread the paint all around and squish and mash it. This helps her see how to play with it. And then I let her do more.
Take it out of the bag to let dry otherwise it will stick.
