@denyceziter, I switched my son today, I dont know if it because of formula but he was screaming non stop. I got scared. Screamed in pain.
I think a.r. means add rice it for baby with sensitive stomach
Yes I use a.n.r only cause she was power puking a.n.r help her keep her food down
that another type of enfamil I think there's also gentle give them a try
