Formula feeding, brown lumps in yellow poo.. normal??

[pickle85]

Hi Everyone!

My little boy Alfie is 2 months old, we formula feed, and have noticed for the last few days he has had little brown lumps in his poo (its generally yellow) They aren't hard, more of a mucousy consistency and are dark yellow/brown.

Just looking for some advise as to whether this is normal?

Thanks all
