We have been long familiar with physical humor (incessant falling down, flatulence, etc.) but last night we were treated to Moses' first witticism that I can recall...over and over and over again.
Mommy: Uh oh. I think that Lily is having a poo poo.
Moses: Lily isn't having a poo poo - you should say she is having a WINNIE the POOH!
Much laughter ensued from his end and we obliged with polite chuckles. I believe we are in for many such jokes in the coming years...I will be working on my mom-laugh.
