belly addiction

The boys love to touch (rub, pinch, etc) my belly a lot. I am not sure exactly where it came from, but they probably picked it up when I was nursing them. They would touch my tummy while I fed them.
I've tried to get them to stop, but it's going slowly. I think it's their security blanket (a blanket would have been much easier). They touch it before sleeping and when they don't see me for a long time (and are tired).

Today, in their nap, Matt was rubbing Nathan's belly :) cute, although in general there is no substitute for mommy's belly
