So I'm getting my breastmilk back and I just want to know how much breast milk should I be feeding my 6 month old thru her bottle I have been doing some supplementing because I was relactating but is she supposed to still have a whole 7 ounce bottle or just try to give her 5 ounces of my breastmilk??
