Jaundice and sleeping

Cris

Baby is a week old now and at first tested positive for jaundice at the hospital but with a second blood test it came back negative. On day 3/4 we noticed her eyes where yellow and then the rest of her so at her newborn check up he said she had breastfeeding jaundice.

Meaning I wasn’t producing enough milk and her levels where low but since she wasn’t eating enough it was clearing out so we had to supplement with formula. Which was fine because that day my milk came in.

My question is, because we are doing half and half she has been sleeping more. And I know my hormones are insane right now but is that normal?

She breastfeeds for about 15/20 minutes, then 2 oz of formula. Sleeps for 2 to 3 hours and does it all over again. She has 2 or 3 awake periods of 45 minutes to an hour

I read jaundice makes you sleepy, I’m just wondering if her sleeping so much is normal ( I know, my hormones make me crazy)
