Baby of 3months old. Having green colour stool... formed consistancy no smell... a febrile. Active. .. intake good..... what is this.?

Green is OK! Baby poop is lots of different colors and can change from day to day for any baby. Amount of bile output varies. One day brown, one day yellow, one green. The worrisome colors are dark black after the first few days of life (cuz your first poop is blackish meconium), red poop or pure white poop. as his digestive tract matures, consistency will also vary. And yes, baby poop may or may not stink!
