Why do baby like to suck their fingers...ahem fist...?

Is it comfort food? Is it delicious? Is it sweet and yummy?? Sophie certianly thinks so! Look at her stuffing her whole fist in her mouth...

What's this? Tastes funny!

Hmm... I think I'm beginning to like it...

What's a baby to do without her fist sucking habits!?

That does it.. I'm gonna ask Mommy for more of these.... err.. fists...
