This morning:

Ava (excited to say goodbye to Daddy) : Wave! Bye!
Ava (after he leaves): Dad! Wave! Bye!
Me: We can't wave to him anymore. He had to go to work.
Ava: Work!
Me: Somebody has to pay for your diapers.

At lunch:

Ava: Dad! Wave!
Me: Dad's at work, sweetie--
Ava: Diapers!
Me: Yes, you're right. He has to pay for your diapers.
Ava: Wipes!
Me: Yes, and your wipes.
