We tried something new during bath time. We started out with a regular bubble bath and then I gave little man a spray bottle half filled with water and (quite a bit) of blue food coloring. He loved it. I wasn't sure if his hands would be able to spray but he had no problem. I was pretty worried it would stain the tub or his skin. It didn't and I was a little surprised.
I thought next time I would give him three different colors to play with but I think I will wait until he is a little older. For now we will stick with our tried and true bath paint!
