Further proof my child is a genius: she has learned how to blow her own nose.
C. doesn't quite have the hang of that yet, and he is almost five. Apparently, though, I have been teaching him all wrong. What you are supposed to do is stick a finger up one nostril and then make snuffling-dog noises until boogers come out the other side. In addition to clearing out the breathing passages, it causes adults to cry "Ew, baby girl" and laugh hysterically all at the same time.
Anything to entertain.
