We're planning to EFF our next LO right from the start and I'm wondering what everyone's favorite formula is. We used Enfamil Gentlease with DD#1 because she had some issues with gas but we're sort of hoping our next LO will take to a less expensive formula I've heard good things about the Walmart brand and also the Costco brand, I think? Also, if we do end up wanting to try a "gentle" or other special type formula, does anyone have any experience with the store brand specials? I know that we'll need to try them out and see if our LO likes them but I'm wondering about everyone else's experiences. Thanks in advance!
