Hi Kathy,
Some tongue movement difficulties are anatomical: a tight lingual
frenulum makes it hard for baby to lift the tonguetip and press milk out
of the breast, so they often compensate by excessive jaw compression.
Some kids have short mandibles, which makes the midtongue tighter, and
makes only the tonguetip able to rise to press the breast to the palate.

Kids with a tongue tie will click when the tongue is pulled off the
breast as the mandible drops, and the negative pressure (seal) in the
mouth is broken.

Low tone makes the tongue bunched or flacid, and reduces movement.  Low
tone kids can thrust the tongue when they try to compensate for the low
tone by "fixing" the tongue.

I could go on for a year.  What you do depends on the cause.  Almost
always, getting the best possible latch with the most tongue contact
possible with the breast helps.  I have writen tons on these issues on
lactnet in the past, feel free to search the archives.
