My 6 yr old comes up to me about an hour ago and says with a very worried look on his face, "Mom! My poop is green."
I asked him what he thought about that. And he shrugged his shoulders. I told him that his poop is green because he has been eating a lot of vegetables and fresh juice - and that it means he is healthy.
He raises his arms up in the air, 'flexes his muscles', does a little celebratory jump and exclaims, "so I am stronger! Oh yah, oh yah!"
