I am really glad things seem to be settling down for you and baby. Long may it continue.
I know lots have people said the same on this thread, but I went through hard time breastfeeding my son in the first 8 weeks, then turned a corner! But it was very difficult and in retrospect I have no idea why I was so stubborn and put myself through that.
I did after around 2 weeks start formula and at that time he went down to 2 bf a day, for a short while, then by around 7 weeks we were back ebf. He didn't put much weight on during this time but it was increasing. (this is not to recommend this to anyone, just to say that even in early weeks supply can be increased WITHOUT expressing - see comments below about my temporary expressing stress!). By six months he was a fairly fat baby and if I tried to explain to anyone about the early days and how he seemed hungry, not putting on weight and fed ALL THE TIME, it just looked like I was being ridiculous as he was so chubby :-)
I got completely obsessed with weight and feeding during this time (first 8 weeks) and only in time could I put it into any type of perspective. You don't sound crazy like I was!
My aim at his birth, was to try and get him to his first 3 lots of jabs. In the end after the corner was turned I fed him for 13 months and believe me I wouldn't have done more than I set out, unless it had become handy and easy.
Anyway I meant to write this to answer your question not tell you all about what happened!

Just as suggestions, hope you don't mind
It only felt like a bit of a bonding experience after ?many months - maybe 4 - and I would absolutely not have bothered breastfeeding for that! There were plenty of other bonding moments and my friends bonded perfectly feeding their babies with a bottle from early days.
I couldn't express hardly anything (perhaps half an oz at most - I tried with electric pump, hospital electric pump, a hand pump or hand expressing, nothing worked - which freaked me out often as I kept thinking there is not much in there) in first 8 weeks, but by the time he was 4 months old I was getting extra if I tried expressing and so started doing milk banking for premature babies who needed it at local hospital. I personally think this may be due to the stress I had got myself into at the time.
Breast compressions seemed to help milk supply (as mentioned before in posts), I kept on with them anyway.
I think they exaggerate how much adding some formula stops you breastfeeding - if you want to continue doing breastfeeds with top ups that may be fine - or split some feeds to breastmilk and some to formula. I've met plenty of mums who found it perfectly possible to continue for as long as they wanted. And in my experience it is possible to reduce formula later if that is what you chose (but I am not telling you to do this, only for info - because I didn't know until I did it) I looked up many websites but through all that time never came to a chat room, no idea why I didn't. Sorry this is so long!
