My 6.5 month old has been exclusively breast fed via a bottle as I pump because my son never latched well.  My supply has significantly lessened and I'm down to my final bottles in my freezer stash so I know by the end of the week, I'm going to have to start supplementing with formula because I just can't keep up with his demand. I'll still continue to pump but I'll have to supplement some of his bottles with formula. (He also eats two meals of puréed vegetables, about 2 oz each meal). What is the best formula to give him? I hate that I wasn't able to keep up my supply but I need to face reality that formula is going to be our future.
