Hoodwinked

My daughter LOVES her thumbs....LOVES them.  If she can have one thumb in her mouth, great; if she can have two thumbs in her mouth, even better.  She puts them in while taking a bath (very tricky to get the soap off before she sticks them in), while playing with her toys, and even while taking a bottle (very messy).
My husband is exploiting this thumb adulation.  He has promised her two extra thumbs....in exchange for no poopy diapers.  The worst part is she believes him despite my valiant attempts to make her see that her father has hoodwinked her.  He has avoided changing a poopy diaper for months.  I realize he only changes one diaper a day, but you'd think sooner or later he'd get a messy one.  Statistics say that he should have to take one for the team once in a while, but no.  I change them, the babysitters change them, the grandmas change them, but not Daddy.
Since he heads out for the field each day, he gets up and spends time with her each morning and changes the first diaper of the day.  It's never anything but wet except for the day I decided to let him sleep in.  On that particular morning, she had the stinkiest poo ever filling her diaper, running up her back, through the sleeper onto the blanket. WHY??????  That is the only morning it's been that way before or since.  Just see if he ever gets to sleep in again!
