I’m having some problems breast feeding.

I had mastitis, bad latch and both nipples cracked and bleeding. Then baby girls jaundice level went from a 10 to an 18. So they told me to supplement some formula in and I did… Through all of that I was still having to nurse her and pump or else my boobs would just ache and be so full. I could pump out 6oz from one side after feeding her…. Within the last two days my supply has plummeted.. one side is completely healed but the other is still healing from the cracks and bleeding…

She started sleeping a long time at night but is up and down a lot throughout the day. (None of my kids ever slept as long as she does at night just over a week old).

Idk what happened… should I wake her up at night, pump more, get lactation cookies?? I’ve ever started trying to make sure I’m eating better and more even though I thought I was eating enough before. I breastfed my second but we had no issues. I couldn’t breastfeed my oldest, my milk came in and was completely gone in a day or two and I was a FTM.. Now I have an 11 & 8 yr old and it’s been so long I don’t remember everything and some of it I just don’t know what to do… All advice appreciated..
