Re: my whole day is feeding
Mama, I think at this point you have an opportunity to decide what really matters to you. Is it maximizing the amount of breastmilk you can give your baby? Is it finding the easiest path forward? Or is it some compromise position between those two extremes?
If you want to maximize the amount of milk you can give your baby, well, then I think you've gotten good advice here. It's all supply and demand, nurse more, pump more, hang in there with the SNS, etc. Not an easy road forward.
If you want to take an easier path and breastfeed only a little or not at all... Well, even this set of choices has some obstacles. The first one would be getting baby to accept the bottle. Try having someone other than you give the bottle, since breastfed babies often hate taking a bottle from mom, since they know she has the "real" thing under her shirt. The second obstacle would be trying to decide how much effort you want to put into nursing and pumping, in order to maintain the supply you have. It can be a lot of work, but if you nurse or pump part-time, you will still give your baby the health benefits of breastmilk and/or breastfeeding, and you will get the health benefits as well.
The two things I want to assure you of are, one, that it is completely normal for a baby to eat every 1-2 hours, no matter what your sisters experienced, and two, that having no life aside from caring for the baby is also very normal... At least in our society, which isolates new moms in such a fundamental way.
I think it's fine to go back to nursing every 3.5 hours and pumping to increase supply. Ordinarily, getting a mom to nurse more, and more often, would be a ticket to increased supply. But if it didn't work for you, that's okay- though I have to suspect that something may be going on with your baby's ability to transfer milk. The fact that you nursed more and supply went down... It implies that something may be going on beyond the hypoplasia, YKWIM? Anyway, if it didn't work, just try something else. If you can sneak in some extra pump sessions, it will probably help a lot: most working moms and most exclusively pumping moms need to hook themselves up around every 2-3 hours in order to maintain supply.
