pretty, pretty names
i remembe dealing with my second child, 36 weeks, jaundice. it was hard with one. i hope you have great support, but ideas anyway in case you don't:
use breast compressions to keep them on a little longer. cup your breast and apply light pressure once their suck rhythm slows down.
switch feed them between breasts so long as that doesn't stress them out. when they have had 'enough' on one side and you've done a compression for them, swap them to the other side (can wake them up a bit)
if one is a better feeder than the other let the weaker twin benefit from her sister's let down initiation by tandem feeding.
have a look at homeopathic remedies. my twins (dc 5&6) were preemies who had jaundice issues and homeopathy cleared it up within a week after we were discharged, praise God. (dc2 took 3 months)
chelidonium is often a key remedy, but check with a homeopathic provider.
enjoy those precious bundles. for all the work they bring, it will
