Great ideas above.

I have taken up a few sub-five year olds. Because of their weight, I
had to fly front seat. The problem then is keeping an eye on the
child because it is nearly impossible to turn around to look (even in
a 2-33).

So I resort to talking about everything and making sure I get
feedback. Phrases like "Weee!" and "How are you doing?" and "Look at
that!" are key. If there ever was a time to know the name of the
child, this is it.

My $0.02.
