Next time they all come to visit ...save up a bushel of old corn cobs.
Corn cobs usually break folks into a "once a day" potty habit. Get mostly red cobs... a few whites are handy for "checking" one's work though.
Phone books work good too, Stay away from glossy paper..not very efficient.
Leafs work ok...stay away from the dreaded leaves of three kinda plants.
You may ask "how does he know this stuff ?" You don't want to know...Ok
Hill, I know better than to ask.
I wasn't born yesterday, so I know glossy paper doesn't work.
FYI....we are GIRLS! We would rather drip dry than use a corn cob. (honestly, what were you thinking)
