Little specs in babys poo?

My daughter is 10 months old. Formula fed, some introduction to solids (mostly purées and Greek yogurt).

I’ve noticed these little black specs in her poo for at least the last 3 days. I dunno if they’ve always been there or if I’m over thinking things. Just looking for some comfort/advice. My husband thinks I’m making a big deal over nothing.

She is eating normal, stools are a normal consistency, she’s

not straining to poo, etc. Totally normal behaviour.
