black poop 11mos

11mos baby ko ... 2days na ganyan pupu nya... Nag fever kasi sya nung june9 to june11, humina sya sa water. And food. June 11 pinacheck ko sa pedia ang sabi po, nagiipin, normal ang labs ng cbc and ua. Ayaw nya uminom water sa training cup nya and bottle. Breastfeed po ako. That day ng check up binigyan sya ng supplements like pro-IG and iron bcomplex. Ni start ko po ung pro-iG june 12 tapos ung iron bcomplex june 13. Tapos june 14 yan na ganyan na poops. Normal po ba ito :( kawawa naman , bloated na. Pero active si baby ko not other symptoms just this ... Thank you po sa mag advice
