Tonight I was urging Julian along in the pre-dinner-handwashing process, and as I often do, I rubbed some water on his face and very lightly squeezed his nose. He cried out in pain and complained that it really hurt. Quite often he has a huge hard snot in there, and that can hurt if there's any external pressure applied. Julian somehow always needs to blow his nose, but Gabriel, rarely.
I pressed lightly on the side of each nostril and asked, "Does it hurt here?" "No," he said, getting over it and walking away, "It's in the spongy bone tissue!"
He's been at that anatomy puzzle book again, it seems.
