"Lucy, why are you crying?"
Not a real question, but I often ask while I am bouncing her, or just so she can hear my voice.
From behind me (and this was more than one child), "Is she hungry?"
"Nope, she just ate."
"Did she burp?"
"Does she need a diaper change?"
"Is she pooping?"
Wow. Makes my heart happy to know that they have learned so much about baby care!
