I've also done that online course. It is not that clear to navigate (or wasn't a few years ago when I did it) because there were some more complex / less patronising tasks tucked away in some of the modules. You saying about the pic of the banana diec - one of the things on Dafne I hated was when they made us play with plastic food portions. I felt it was utterly degrading for a bunch of adults (and I told them so!).
spotty thankfully I have a lactation consultant already. She had seen me ante natally to help me with the colostrum expression and came to the hosp twice while we were in. She is coming again tomorrow which is great to work on teddy's latch which is improving but is very pinchy. She's also referred me to a tongue tie person as he has about a 50% tt. Hosp said it was not an issue but I def think it is hindering how well he feeds from me. Finally we're seeing a cranial osteopath as Ted has quite a tight mouth / jaw which again is making it tough for him to latch really well and contributing to the pinching.
My DH has been such a star. He is managing our timetable for feeds and pumping, doing all the cup feeds, sterilising everything, feeding me, making sure i nap and generally being wonderful. I couldn't have wished for better support. 
Can't wait to drop the pumping and cup feeds - it will mean I'm one hour on and two hours off instead of the other way around. Ted seems to be getting better at feeding from the breast each time so hopefully sorting out the tt and getting to the osteo will make all the difference and let us drop the cup!
