First of all, this too will pass.  Patience.  However, why not try *longer*
feedings, if possible.  I know that sometimes these babies just pull off the
breast when they are finished, but they might do better just being allowed
to fall asleep at the breast and allowed to pull off or go completely asleep
at the breast, with *no* burping or interruption of the feeding. If that
doesn't work, try the same approach with two feedings/side (with expression
of just enough milk to remain comfortable on the opposite side).
