Did You Know a Good Way to Wet Watercolor Paints for a Toddler?

Did you know a good way to wet watercolor paints with a toddler?

Today I let the toddler do some watercolor painting. She mostly wanted to keep dipping the brush in the water which ended up cleaning off the paint causing her to paint mostly with water. So instead of having her dip the brush into the water, I wet each color of paint with some water from a medicine dropper. (She was not concerned about not mixing colors; in fact she mostly wanted to mix the colors.) It ended up being a bit better for her and less messy overall. And prevented a power struggle over the paint brush in a cup of water!
