Chanita brings up some interesting logistical questions: "  if the same twin
is always the second twin is he getting cheated out of the available
colostrum at first, until mom's supply increases?"  Theoretically the first
twin could get more colostrum than the other until mom's rate of milk
synthesis increases.

        "if the same twin is always the second twin, is he getting a bonus
of all the hindmilk, while first twin gets mostly foremilk, once the mature
milk is there?"   Yes, in theory this could happen, as above.

"Should we encourage moms to feed one baby on one side, the second baby on
the other, then switch at the next feeding time?"   Yes, encourage mom to
give one baby per breast.  She can change at every feed, but if the babies
have totally different patterns (a likely occurrence!) it may be easier for,
say, Twin I to have the L breast for a whole 24 hours, then for Twin II to
have the L breast the next 24 hours.

" Or should they feed each  baby both sides one right after the other?"  No,
much easier (and more logical) for each baby to practice unilateral BF, but
change breasts after 24 hours.  Ensuring that each baby takes both breasts
at each feeding, and then working out which one had fed first so the *other*
could have first crack next time might stretch mom's deductive capabilities
somewhat!

It can be a little confusing and of course there are no absolute rules - if
mom "forgets" which breast which baby had then the world won't end, but
generally speaking if one baby is not breastfeeding so well then "his"
breast will remain fuller, and perhaps remind mom to feed this baby more
frequently, or for longer.
While both babies are learning to breastfeed it can sometimes help to give
the less competent baby the "easiest" breast, perhaps for a few days.  If
babies are still learning how to latch, breastfeeding each one consecutively
can be easier. Once both babies can latch and stay attached, simultaneous
breastfeeding will save mom hours of time.  This can also be helpful if the
babies are very different in their capabilities, in that a stronger twin
will stimulate the let-down for both breasts and a weaker twin can benefit
from this, he simply drinks as it occurs.  It would be a good idea though to
give each baby a chance at each breast over time because a stronger hungrier
twin consistently fed on say the L breast for a long time would generate a
good supply, but a weaker twin on the R would leave more milk behind and so
depress the supply.  While it could seem to be an idea to give each baby his
"own" breast consistently to avoid confusion mom would need to change the
babies' positions, i e football hold sometimes, cradle hold sometimes, so
that each baby obtains L & R hand/eye stimulation.

"How complex it gets...."  Yes, it can seem overwhelming to a new mom, but I
find they usually get very organized very quickly.  Mom can ask Dad to keep
a chart of who gets what breast, how long whoever feeds, wets, stools etc.
for a few days until it is clear that *both* babies are breastfeeding well.
Later she can stick this record in the babies' Baby-book, and marvel that
she accomplished all this!!
