I think Dr. Newman has this as one of his "myths". He says its ok to mix. I would imagine to be a "purist" you would not want to mix and adulterate ebm in any way, especially like what has already been said about possibly wasting any ebm. What about bf with a supplementer tube that has formula in it? You could bf first then open up the clamp of the supplementer later if you didn't want to mix. I think what his myth thing is saying is that in reality mom's who have to supplement need an okay to do it easily and not worry so much about the "purist" aspects of this (for lack of better word). And hopefully, many, if not most, supplementing can eventually be eliminated and go to exclusive bf. I think it is more a problem for sick and preterm babies to get the optimum nutrition and infection fighting benefits. Seems more research is needed here. I am really enjoying lactnet discussions lately. Hope the new posters will continue to contribute. We are really a nice bunch of folks so don't worry.
