formula feeding moms

For anyone doing formula I was wondering what formula has been recommended to you or which you prefer. Similac of Enfamil. Powder or pre made. Are you buying the formula before baby gets here or waiting to see. FTM here just wondering how everyone decides a formula. And YES i do know the benefits of breast feeding and NO I don't care what you have to say about it. I have my own reasons on why I will not be breast feeding, so before you start, know that nothing you say will change my mind ❤️☺️
