Hi Oncemore, I logged on here to post about my own misery and ask for advice and I'm really grateful you posted this because there are some similarities to my situ - and yes, it feels like climbing a mountain, doesn't it? Really punishing.
My first baby is now 8 wks and he couldn't latch at all from day one, due (I think, in hindsight) to a combination of high jaundice very quickly, sleepiness, undiagnosed tongue tie and a bit of shock to us both after a traumatic birth. After 24 hrs of trying to latch him on, the paed Dr told us to put him on formula bottles urgently as the jaundice was so bad and he had low blood sugar, was sleeping non stop. I felt horrendous, like I had been so focussed on trying to bf that I dropped the ball and actually deprived my DS of food. We had 5 hellish days in hospital while he was treated for jaundice and I bruised my breasts hand expressing colostrum and later pumping milk every 3 hrs round the clock. I spent more time with the pump than I did holding my new baby, and I WISH someone had told me then that what type of milk your baby gets is completely insignificant compared to how many minutes or hours you can hold them close to you and enjoy them. Anyway, after getting home I kept pumping so we could bottle feed him my EBM. The only way he could latch on was with a nipple shield, so we mixed feeding with nipple shield and top up with either EBM or formula. Because f the jaundice he was on a strict 3h feeding plan to get a certain amount of fluid through him.
At 3 wks we saw a private lactation consultant who treated his tongue tie and put me on a regime of 3 capsules of fenugreek three times a day plus 10mg domperidome 3 times day plus pumping every 3 hours. I managed that for 2 weeks but it nearly killed us all, an almost impossible strain and I very nearly gave up and switched to formula. Funnily enough the closer I came to accepting I would have to give up, the more my milk supply increased. Over those 2 weeks my supply went up so much that I could feed him 8 bottles of 110ml EBM each day. At this point the paed Dr said I had enough milk and could switch him to fully bf with the shield, keeping to the same 3hr schedule and getting weighed each week to check he was still gaining. She told me to keep pumping 3 times a day plus 1 pump between 1am to 5am when prolactin is at its highest peak. Amazingly, we switched to exclusively bf in just 24 hours and had 10 days of blissful feeding!
However I then made the mistake of pulling out the supporting props too quickly - I stopped taking the fenugreek, domperidome and stopped all but one pumping session - I stopped everything within the space of about 5 days. Big mistake. Two days later my supply must have dropped because DS took the breast for only 5 mins or so before pulling off, uninterested. (I think as well as supply, he may have got a taste for the fenugreek in my milk - I'm taking so much that my skin stinks of it, so pretty sure my milk must too).
So on the advice of a BF counsellor I quickly put back in all the above, and within a few days he was feeding ok again.
SO ... I would say ... yes, some women can increase their supply and if you want to keep trying then what you're doing now is the best way I think to go about it. I would encourage you to add in a pumping session between 1am and 4am though, but I hate even writing that to you because I know what a killer it is.
But all the above is the technical stuff, and doesn't really address the heart question - should you keep on trying or switch to formula. I wish I knew the answer. I'm currently wrestling with the question again as my DS can still only feed with the shields and they are such a laborious thing to use and I find it almost impossible to feed him in public with them as they are awkward to put on, he knocks them off, they spill milk all over my clothes at the end of the feed ... and at the core of it I feel ashamed for anyone to see me with a piece of latex over my boob, as if my body is defective or something ... bf is such a highly personal and intimate thing. In the past week, since trying at bf groups to teach DS how to latch onto me rather than a shield (no joy yet), there have been screaming fights at the breast and struggles to the stage where I have given up on some feeds and given him a bottle, because I just can't take anymore. I'm still pumping 4 times a day and taking the meds. My question is will he ever learn to latch on without the shields or will I have to keep chained to my house feeding him with the shields and then pumping ... because the prospect of that is miserable.
I'm aware I have poured out my own story at length in response to your post ... sorry, I'm too tired after DS being up all night to go back and edit it for stuff that's pertinent to you, so you've got my whole story in a blurt.
I know in my heart that the most important thing is to give my baby love and cuddles, and food comes second to that. I am still struggling in my heart to accept that bf has not worked for us and that I need to grieve the longing and let it go so we can move on. Day by day, as you make your decision, choose the options in each moment of the day which allow you the most time to be close to your baby. Everything else is secobd to that. Good luck!!
