They would be smart to make them toddler size and market to parents though. Every parent only wants what is best for their little one and - as you know - when the little one won't eat healthy parents will try anything. I'm thinking this qualifies as an anything. LOL
I think you are right. I wouldn't. I don't know, something about vitamin underware just doesn't sit well with me. LOL!!! But they would definitely have a huge market. :)
