Need to find another formula !

Alexandria

So I need to find another formula for spit up, I haven’t been able to find the enfamil A.R can anywhere and I had ordered online but it got delayed. My sons dr was suppose to call me back on a suggestion for another formula he can take but she never did !!!!

What’s similar to it ??? What’s the target brand ??

The Walmart brand has been out of stock around here for 2 months already
