Suggestions formula milk for newborn

We started with Nan Optipro HA FM and everything is ok but at about 2 months+ my baby started to have watery greenish poo that lasted for a few days so we immediately changed it to S26 FM and everything is ok so far. She is 4 months+ now.

I gave my baby enfamil and everything's so far so good since newborn till now 4 months old. Poops regularly daily at least once a day or sometimes twice a day. Previously on similac but got runny stools

my baby girl feeding on enfamil since newborn, till now 5mth old still feeding on enfamil, u can purchase a smaller can for yr baby to try

Nan if not isomil (soy milk) Buy a small bottle to try first. Trial and error. My first boy change 3 times

How did u change his milk? Literally changed or mix first?

Enfamil works for my LO

Similac

Nan?
