Splash!

I sometimes joke that I'm part duck because I love rainy weather. I'm starting to wonder if Relia hasn't picked up some of my waterfowlness. If we let her wander around with a sippy cup she will eventually pry off the cover and make a puddle. If she can't pry off the cover than she shakes the milk out for the same effect. After she has the puddle she slaps it to make it splash further.
To combat this I've taken to giving her a no-pry lid with a rubber stopper in it. The stopper will only let water out if she sucks on it. For the past few minutes she's been trying to shake that water out on her favorite chair. No luck but she's still trying it.
Should we sign her up for swimming lessons or something?

UPDATE: She just got the lid off of a cup of milk. Yay! Great fun. And then Mommy and Daddy cleaned it all up. Then she took the cup and realized she had nothing to drink. That led her to, you guessed it, cry over the spilt milk.
