This morning, as I was pulling out of the driveway, I could see my girls in the window.
Ambria has learned to prop herself up by standing on the heater vent and hold on to the window ledge. Mariah was waiving hysterically, and I simply had to put it in neutral and press pause.
I waived in return, blowing kisses (Mariah catches them). Ambria, through learned behavior, imitated the waiving. But to do so required her to step down (out of sight), releasing her otherwise occupied hands.
As I pulled down the street, I saw her tiny hands waiving, where her face once smiled.
