Water painting for toddlers!

Ever painted with a 2 year old? Highly stressful. We were painting rocks today thinking of making monster rocks or angry bird rocks when my 2 year old got mad and through his brush full of black paint. We had a towel down but I was still letting him know we don't throw and that now he has to watch us. He then decided to throw the paints, which we all connected of course. Ugh.
Now both boys are crying and unhappy. I am feeling overwhelmed and frazzled when I remembered a pinterest toddler activity of painting with water. I skipped over it before because I never thought he would enjoy it but I figured it would be worth a try.
I gave callen the dog bowl full of ware and a sponge brush. He painted the deck and was extremely pleased with himself. This made it able for me to pick up, get Carter a different set o paints and get him started. Callen enjoyed it for an hour! Wow! He even went back to it on his own this evening! Another great idea! So, don't doubt the activities you find from at home moms, home schooled moms etc...they know what works!!! :) it saved me, my boys and my sanity!
