Learning to say "Adam"

Last night Daiken woke up around 3:00 AM and Adam went in to console him. He was screaming for me, of course, so I got out of bed to see what I could do to help. Adam headed back to bed. After a minute or two, Daiken was still having a hard time calming down. Estee started stirring. So I called out to Adam to see if he would come try to keep Estee quite so she could stay asleep. But as I called "Adam?" I heard an echo..."Agah!" and then silence as if waiting for a response. After no response from Adam, I could hear Estee calling again, and again, "Agah!" pause, "Agah!" pause, "Agah!" It was so funny to me. Estee, wide a wake at 3:00 in the morning was learning to say her Father's name! Silly girl.
