To follow up to my last post, thank goodness for magic erasers. Austin went on a coloring spree this morning while I was loading the dishwasher and my bedroom wall and door looked like the set from Elmo's World. I asked the ladies at WebMD for advice and they told me to get a Mr. Clean Magic Eraser and sure enough, it works like magic. I think I will get some to keep in the diaper bag for when we travel too. Awesome product!
