1 c old fashioned, quick cooking, or instant oatmeal
Grind your oatmeal in a coffee grinder or food processor. Put in your oats and grind until they are a fine powder. If you would like to make a large batch of powder you can grind in smaller batches and store in a jar with a lid for up to 6 months in a cool place. Add 1/2 – 1 c directly to your bath water or about a 1/3 c to a baby bath and swirl around with your hand. The water will look milky and feel silky. In a powdered form the oats will go down the drain without any problems.
If you don’t want to or can’t grind your oats you can add 1 – 2 cups whole old fashioned oats to a sock, knot the sock just above the oats so they are snug in the sock, and put it all in your bath for 15 – 20 minutes. Wring out the sock several times. Oatmeal powder will make your tub more slippery than usual, so take care.
