Bodywork made the difference for us
You are not obsessive, you are not a lunatic. You are fighting and using your resources to do what's best for your baby. He DOES want to nurse, he just needs a lot of help from you. You are doing the right thing, the important thing and most importantly, the thing that feels right to you. Mother's instincts are so important, and you are paying attention to them for all the right reasons. Give yourself some grace.
Shame on your mom and your mate for giving up on you; perhaps they don't understand how important it is, but ultimately, they're making it harder by not having your back. I'm sorry.
Only you can make the decision of where to draw lines, but I encourage you to give the CST a try. I haven't read all the PPs, but do see one that suggested selling some of the stuff you've bought but aren't using to fund the CST...that's a great idea!
I just wanted to share that bodywork pretty much "saved the day" for my nursling. My son had a very rough start to nursing...we had an easy birthing, but he was a bit early and immature, and didn't nurse effectively; he developed severe jaundice and had to be hospitalized. My milk still wasn't in by a week. He lost a lot of weight and we had to supplement with donor milk for a few weeks while we worked on measures to increase my supply (a lot the stuff you're doing) and improve his latch (high palate, not opening wide). I was reaching a point where it seemed ridiculous to be spending so much $$ on pump, LCs, herbs and donor milk, but I wasn't giving up.
At 3 weeks of age, we saw a DO for cranial osteopathy, which is very similar to CST. She gently readjusted his cranial bones and jaw. After the first session, I nursed him and for the first time EVER, felt a strong pull on my nipple with no pain. His chin was practically on his chest, milk was leaking out of the corners of his mouth and he was looking up like "whoa mama, this never happened before!" He had one more visit with the DO and has had a few chiro adjustments. By 6 weeks old, he was off all supplements of donor milk and totally on my breast for all feedings. I also was able to wean all the herbs and pumping.
So, in my opinion, go for it! I know that I would have been regretful if I hadn't tried that one last thing (knowing what I know now). Also, consider a milk donor if you need to supplement...at least then your LO is getting human milk in addition to your milk. We got ours from a milk bank, but I know there are a lot of women giving it away to other moms too.
I wish you the best, and look forward to hearing more. Feel free to PM if you have any questions for me.
