Bye bye seedy poop???

Ka

My son has been a formula fed baby since day 1 because I am unable to breastfeed. We recently introduced him to rice cereal about 1 week ago. But I’ve noticed over the past month the amount of seeds in his poop decreasing and now they are gone.

Is that normal? Everything I try to research only comes up with breast fed babies. I can’t find anything on formula fed yet
