I have worked with far too many babies now who have have instrumental
deliveries or excessive oral suctioning at birth who then don't feed well -
some do, but many don't.
The management you have been doing to date sounds good - the use of bottles
after 5 days is just one of those things that nobody but the likes of us can
see a problem with :-(  and she may not have continued with breastfeeding at
all if not given this option.
Co-bathing is what I have the most success with - the research on it has
been published in Breastfeed Review, if you must have research.  What this
involves is mum and baby bathing together, pleasantly warm water with baby
on mum's chest.  An assistant can be there with a jug pouring warm water
over both to make sure they stay warm.  More times then not I have had the
baby self-attach, or attach and suckle really well with mimimal assistance.
It's kind of like giving the baby the birthing experience and opportunities
it didn't have.
And if the baby doesn't feed, you've got a mum and baby who have had a
lovely relaxing bonding experience together.  And that is another factor to
consider in this relationship - she's had a traumatic birthing experience,
probably has genital trauma of some description, went through varying
amounts of pain and now this ungrateful baby isn't doing what it should.
Maybe it's her fault, maybe it's the baby's -  these are thoughts that are
going through her mind.  The bath can help in more ways than one - and of
course heaps of talk about how marvellous she is and how gorgeous the baby
is, and all these problems will be sorted out in time.

I've just re-read Betty's post and think perhaps I'm off course on this one
anyway as it had been feeding prior to lactogenesis II.  On re-read it
sounds more like baby is breast refusing due to overactive milk ejection,
got a fright at the breast and now won't go back on.  My suggestions would
be all the usual breast refusal tricks to get baby to attach, but to feed
baby in an upright position so he can handle the flow a little better and to
make sure that no one has a hand on the back of his head!!!!

Sorry to rave on so...  hope it helps
