"In these debates there are often posts about the childs diet after they begin eating solid foods, as if people who FF go on to feed their child a perfect diet, and people who breastfeed go on to feed thier child noting but McDonalds."
I don't think anyone has said that have they? I think its making the general point that child nutrition doesn't begin and end with bf.
I think these debates go round and round in circles to be honest.
I would love to have exclusively bf DD, that is what I planned to do. It didn't work out that way for me despite trying very hard. So I did the best I could.
Now going back to the original question, I may have fed DD artificial food/milk but I don't see it as "artifical feeding". A subtle but important point IMO.
