#3 has recently developed an affinity for flushing his underwear down the toilet, so the plunger and I have gotten to be good friends.
A few days ago he tried to flush five pair at the same time, and it overflowed the bathroom. Tonight when I was doing the dishes I heard him in the bathroom saying, "Bye bye underwear!" so I came running. Fortunately, I caught him at the first pair (I think).
The potty training process has been a long, slow, tedious one, so I don't want to do anything to discourage his interest in the potty, but this is ridiculous! :)
