baby starts to suck her fist March 15,2012

I noticed today baby started to suck her fist.

 

Por por said it is good for her motor skill (using her hand) and her needs of comfort.Don't need to stop her to do so. Por por told me if she sucks her fist ,she will continue to suck her fists.Some babies like to suck their fingers instead of fists,we will see it is true or not.
