But kmac he's put on weight which I think is brilliant and please see that as a positive. I have no idea how much 30g is as I didn't lbs/ozs but I wouldn't expect to see loads in just four days anyway. I feel that you have become (through no fault of your own) really really stressed about this weight issue and if he is weeing/pooing regularly and developing well and thriving then I really would try to not worry about it (I know easier said than done).
You do sound at the end of your tether and really defeated though, and I don't think anyone could say you hadn't put 100% into your efforts to breastfeed. If you need to top up as well as breastfeeding or you have just had it with the whole thing then ultimately that's your decision, but I think you would need to have a really good think about how that would effect you mentally and emotionally? I've seen so many women on here give up (sorry not good way to phrase it, but can't think how else to say stop breastfeeding after battling) and feel so awful for weeks/months afterwards.
Re. you not producing enough, although its easy for me to say, I think you are. There have been some breastfeeders on here as noted above who have not been able to produce anything from either kind of pump. Its not necessarily an indication of how much milk you are producing.
Re. your Mum - it sounds like the visit is going to confuse you even more as your Mum just wants you to be happy and start to enjoy your baby but I strongly believe that she should be encouraging you to keep going. If I was you I'd be economical with the truth and try to steer clear of the subject if possible, or delay her visit for a week or so?
From knowing you just a wee bit (sorry if this is presumptuous), I don't think in your heart of hearts, you are ready to switch to formula 100%, I think give it a few more weeks of feeding on demand and everything will just fall into place. You do sound absolutely exhausted and defeated, it really is hard work isn't it, but I think you can do this. Try and sleep as much as possible in the evenings or when Kian sleeps during the day or at the weekends to build up your strength.
to you, I'm behind you whatever you decide to do, but have faith that you can do this! I wouldn't be helping you at this moment in time if I told you you should switch to formula, as that's got to be your decision, but for what its worth, I think you can break the breastfeeding.
Lots of love
