Baby potty

Is it just me or do all babies prefer to poop only once they've been picked up? I swear for the last few days he only poops if I'm holding him. Part of me wants to believe he's potty training himself and he'll be out of diapers faster than any baby ever...just have to wait for him to be able to sit up/walk to the potty, and that I"m his training potty. haha Well I have to tell myself something and that is preferable to mommy looks like a toilet ():o)
