Z figured out how to pick her nose this week. I've caught her with her finger up a nostril a few times in the past few days. The first time, I tried sounding casual, "Hey sweetie, what are you doing?"
"I'm just taking out boogers, Mommy," she replied, wiping one on my husband's side of the bed.
"But we don't put our fingers up our nose. You can get the boogers with a Kleenex."
"It doesn't work as well," she said, pointing out the obvious as her finger headed back upward.
