Hmm, that is very poor. It would be really useful to know what organisation she was from.
The thing with correct positioning and attachment is that it can look ok but not be ok (similarly it can look "wrong" but be fine). Looking is only part of the picture and needs to be combined with a number of other factors, including how you as the mother are feeling about the latch.
Are you still wanting to directly breastfeed? Can anyone here help? Can you tell us more detail about how your baby won't feed?
It is perfectly possible to exclusively express for your baby. Most people find it a harder alternative to direct breastfeeding, but not all. It is usually crucial in the early days to express very, very frequently, day and night, 10-12 times in 24 hours (so that's nearly every 2 hours). This is because pumps are less effective at removing milk than your baby (when feeding well) and it is critical to "set" your body's milk production at a high enough level to make enough milk as he or she grows bigger. It doesn't matter at this point if that number of expressions is making way more milk than you need - just freeze it. You will either get through it, or you could consider donating it, but it's far more important to get the production kick started.
After the first 5-7 weeks (no sooner) you can start to play around and reduce the number of expressions but still retain a couple overnight for a while as that's a really critical time for telling your body to produce plenty (as night feeds are important).
Using a double pump may be most efficient and effective.
Hopefully you will be able to get your baby back to the breast directly, though, as this is usually much easier.
Do post again if there's anything that anyone can help with. Good luck xxx
