Black stuff in baby’s poop??🥺😥

savanna • Mommy to my baby boy 👶🏻🤰🏻 7/14/19💙

I’m so confused ?! What is this I am so worried ): he’s EBF and hasn’t had any solids or anything at all ever!! 😥😥 it’s definitely black not brown either before someone says it

Nipples aren’t cracked or bleeding either. He’s 4 months
