Switching nutramigen formula

Anyone switched formula from nutramigen to something else?

This damn formula is so expensive & my LO no longer has a sensitive stomach (eating purées & pretty much anything snack wise with no problems) I have switched to enfamil gentlease & she will not drink it.

Just curious to see if any other parents have success with switching to a different formula that’s also cost effective. Maybe the taste is so different to her?

Thank you all!
