Mardrey,
I have seen a baby with tongue tremors, though the one I saw tremored at the
end of a decent burst of suckling (10-15 sucks).  The most helpful thing we
did was to support this little one well in a football hold (gives good
stability for better use of oral muscles), and use a finger to provide
sublingual support - a finger from the hand supporting the breast is held
forward under the chin, gently supporting the d=soft tissue of the tongue from
underneathe.
        Two possible reasons for tremors of the tongue in an otherwise
neurologically healthy child:  low tone of the tongue, necessitating "fixing"
or holding the tongue strongly, which generates muscle fatigue, the fatigued
muscles trmble.  OR compression of the hypoglossal nerve, which passes closest
to the bony structures of the foramen magnum of all the cranial nerves and
will be affected first by a little "mashing" during birth.  Of course, you
could see these same things in a child with a neuro problem, but it is hard to
tell a slightly immature nervous system from a mild neuro problem....
Keep us posted.
