My son, even at 9 years old still uses his shirt as a napkin or a towel, and he puts the neck of the shirt in his mouth on occasion when he is anxious.
After reading Clean Planet, Clean House, she said that stain stick was the one evil she used as she could never make something or buy something earth friendly that actually worked. She recommended the Spray N Wash Stain Stick. My target and Walmart recently stopped sellling them. I panicked because they actually work!!! I can only find them at the grocery store (for slightly more, of course.) I bought 8 the other day because I got scared that they are going to be discontinued or something!
