I have never seen this happen...I'm cycling through my frozen breast milk still and am currently finishing up October's stash. I took a bottle out at 630p and fed the baby at 7. He left 2 ounces in the bottle, so I left it out so he could finish it at his 1030p feeding, like I do every night. However, when I went to prepare more bottles, I noticed that this bottle was almost neon yellow. I thought it was just the lighting so I took it over to the sink and the top layer was literally yellow....like butter! I threw it out because I'd rather be safe than sorry. I've never see anything like this. Have you? I don't think it was bad to begin with because it had no smell and my little guy drank almost 4oz of it.
Thoughts?
Re: Yellow BM??
The color change could be due to what you ate when you pumped (especially B-complex vitamins).
But, more importantly, once LO starts a bottle, it should be finished within an hour and any remainders discarded. Bacteria will build up in the nipple and bottle from saliva. When my LO in the NICU there was a baby there who got sick and hospitalized after mom feeding a bottle hours after it was started.
Thanks...I just haven't seen the yellow before.
As far as throwing out whatever's not finished -- I hadn't heard about that either!! I'm thankful he hasn't gotten ill in the past 3 months we've been letting him finish his leftovers!!
Actually the 1 hr rule only applies to formula. You can safely use breastmilk at the next feeding if there is leftover, but it should be tossed after that.
