Baby poop formula fed

Hi mommies... my baby is 18 days old. formula fed since day 1. drank dulac, was ok at first and then had hard poo, changed to Grow cos that was what KK gave, was ok, poop was soft and creamy. and then his poo changed to mucus like + seedy. he poops almost after every feeding. changed to friso now, mucus poo + seedy. is this normal? 😞 Pictures attached. (sorry for the pics!)
