My son was recently handed down an old t-shirt with the Teenage Mutant Ninja Turtles on it. Now, that's fine by me ... I love hand-me-downs, and I think those Turtles are pretty radical, you know?
My problem arises from the fact that he never, ever wants to take the shirt off. He wants to sleep in it, go to family gatherings in it, even go swimming in it!! No matter the amount of dirt, grime, peanut butter and jelly, or chocolate on that t-shirt ... it's a fight to get him to take it off for me to wash it. And he's usually a pretty dirt-phobic little boy.
I'm pretty sure it's not gonna cause any psychological damage if I MAKE him wash it every once in a while, but I sure hate the fight that it causes!
