I NEED HELP!

So, my monkey pants is 21/22 months old.  She loves to be a Big Girl, but she's just not ready for potty training yet.  That said, she HATES having a poopy diaper.  I don't blame her, and this usually isn't a problem if she's awake when she fills her shorts.  However, if she's taking a nap (which is usually when she has her poops), then she'll wake up and smear the poop everywhere in an effort to wipe it off.  EVERYWHERE!  Hair, arms, legs, toys, bed, wall, crib rails, etc.  Any ideas?  Seriously, I'm up for anything at this point.
