But my favorite feature of thumbs is the wonderful way they fit right into a child's mouth. It is almost as if God created a perfect fit between thumb and curved palate, the fit that provides instant comfort in times of tiredness, distress or hunger.
And that is the fit that my youngest has discovered and exploited. Thanks to his thumb, Edwin can now sleep from when I put him down at 5 pm (with a feeding when I go to bed where he may or may not wake up) until I check to see if he's still breathing around 6:3o or 7. Orthodontia may be somewhat expensive, but as my mother has said before, long-term psychiatric care is very expensive.
