Marley has discoverd the "extra part" that we girls do not have. And like most men, he is completely obsessed with it! During diaper changes he proudly grabs it asking "What's this?" To which I reply "That's your penis." I think he already has the mind of teenager because everytime I say the word he laughs!! You can also see he must ascertain its existence even with clothes on!
Man I can't wait to show this to peopple when he's 16...man...he's gonna LOVE that!!
