I'm slow

Another milestone* coming our way.  I'm attempting to teach the twins to use "big" cups.  Kinsley is doing great, Eligh is learning (spilling water on his shirt and the floor). 

I keep reminding them to drink slow. 

Their response:

"Mommy, I'm slooow!  Look!  I'm slooowww!  YAY!"

*(I wish I could say it was potty training that we were successfully managing, but I've given up on that until summer or longer).
