I am so happy that you have another bubba on the way hun, congratulations. Normally I'd advise joining the ABA but I think you have that covered

One thing to keep in mind is that all babies are different. Just because your DD wasn't able to draw the nipple out well from birth doesn't mean baby 2 will have the same problem. I'm sure you've read about my nipple story before - how when DS1 couldn't attach due to a tongue-tie I was repeatedly told I had flat nipples, but when DS2 attached for the first time straight after birth, the mw told me I had great nipples for breastfeeding. Same nipples, different baby.

Also, as has been mentioned, skin to skin at birth or as soon as possible, Baby Led Attachment etc are all very helpful.

I so hope that this is an easier start to feeding for you. I know you are determined enough to make it work no matter what happens!!
