I've read that bloody nipples can cause bloody spitup or stool so that sounds like what you're experiencing.
I can see how that would be scary though!
re: pumping (based on my conversations with my Lactation Consultant, because I'm definitely no expert haha), it kind of varies on the advice given for pumping. I was told to begin pumping immediately, but that's because Aria didn't start nursing until she was almost a week old and the LC didn't want me to lose my supply by just ignoring my boobs (since Aria was just fine ignoring them,
) But she said she doesn't usually tell women to pump so early, if they're having success with nursing. I just was lacking in the success department for a week.
So I've been pumping since day one in the hospital, though I no longer do it routinely. I was pumping every 2 hours to establish my supply, then as soon as she began nursing on her own, I've cut back dramatically and just pump occasionally, when I feel inclined. My LC said normally they'd say not to introduce a bottle of EBM until 6 weeks to avoid nipple confusion, but since Aria started on a bottle, she could care less. She prefers the boob, actually, but will reluctantly nurse from a bottle if I try.
I'm still pumping because I want to stockpile a supply for myself. I have worked it out with my boss that I'm working one Saturday a quarter to keep employment with the company - so if I decide to return to work after 2-3 years, even just parttime, I have my foot in the door - with the option to work a few weekdays through the year as well. I've accepted it, because I love my boss and co-workers and would consider returning there when Aria goes to preschool - and eventually school. I don't start until April, so I want milk stored for that time - so she'll have whatever she needs all ready for her. OH did give her a bottle the other night because I accidentally woke him up while I was puking in the middle of the night, but that was a fluke. lol! Not that he is opposed to helping me, but since it's tax season + longer hours for him, I felt guilty that she kept him up for 2 hours in the middle of the night. Though it was nice to get a short break!
I digress, lol; pumping can throw your supply, and speaking from experience, oversupply does really suck sometimes. That's why I've cut back on my pumping immensely, because it's not a fun experience with which to deal. Her cluster feeds have thrown my body back off-track on their own, though, so I can't really win.
Mornings are, from what I understand, best for pumping milk.
What I had been told was 10-15 minutes per side, and not to worry about quantity of milk during that time. Some women can pump a lot, some can't pump much at all, and I've found that sometimes I can get 3 oz easily per boob in about 5 minutes, and other times in 15 minutes I can barely get an ounce. Just depends on various factors. I basically pump until I have at least 6 oz in my fridge, then I freeze it. My bags hold 6oz but sometimes I wait until I have enough for 2 bags, even if one isn't a full 6, then freeze. Just depends on how much pumping I plan to do during those 1-2 days.
In terms of balancing it out, I've yet to master that, so I'm not sure what to say.
haha. I'm trying to combat my oversupply and it's a tedious and un-fun process. So hopefully someone else with more experience with that will be able to give you good advice. lol!
