Breastmilk poop didn’t wash out??

Judith

Okay it was my very first ever poopy cloth diaper. I ran it through the wash TWICE and I’m confused as to why this happened. My baby is only 3 months old and only gets breastmilk. Did I do something wrong or forget a step? I mean I didn’t let it sit out too long? Idgi. I used Tide original.
