Anne,
I have seen several sets of twins with suck problems.  One pair of
identical twin girls were both tongue-tied, one more severely than the
other.  The remainder of the twin pairs had only one twin with a
problem. One was a hypotonic baby who responded well to strong flexion
at the breast, and being carried in flexion around the house and laid on
his back with his shoulders on a half roll to play.  Another twin seemed
to be neurologically immature and was helped by preparatory handling
(rocking or bouncing) before feeds and some jaw support, she also had
cow milk allergies, which her (fraternal) twin did not.  Yet another
twin pair consisted of a girl who was gaining well and a boy who was
failing to thrive.  I recommended mom position the girl first, supported
by pillows, and then use both hands to support the boy at the breast.
We also used some oral stimulation to improve his tongue tone and
strength. At one year of age he was diagnosed with several minor
neurological problems, including Horner's syndrome and ipsilateral
muscular weakness.  He continues to grow and develop more slowly than
his twin sister, but is within normal limits.
        Has the mom of twins that you posted about tried pumping after feeds
and using that hindmilk as a complement?  If there is a metabolic
problem, supplementing with abm usually makes it worse.
