Chris,
I have had several sets of twins in my practice where one has difficulty sucking
correctly and the other does not.  Sometimes the mother can position the more skillful
twin at breast, supported by pillows, then use both hands to position the problematic
twin.  The stronger twin can assist the other by producing a milk ejection reflex.
        This sucking problem sounds like it is due to the baby's tongue.  High palate is
a symptom (in my humble opinion) of a tongue that does not reach the palate or is not
strong enough to spread it.  The fact that the baby was always falling off the breast
would lead me to beleive that Joey might have low tone in his mouth/tongue, or a
restrictive frenulum (yes, even identical twins can have slightly different frenula
lengths, I have seen this too, both tight, but one looser than the other).  A
restrictive frenulum can also restrict mouth opening.
