Hi mama! Ang black seeds sa poop ng baby ay usually normal, madalas yan kung exclusively breastfed siya, and a few of us moms noticed the same thing sa aming babies around that age, nothing to worry about. But since baby is 6 months na rin, best to mention it sa pediatrician mo during the next check-up just to be safe, lalo na if may iba pang changes sa behavior or feeding niya.
