I take "artificial feeding" to mean bottle/cup/tube feeding though. So could be formula, could be EBM, and could be for very good reasons (ie, prem baby needing tube fed or whatever).
So no, I don't have a problem with it. But then I'm not mad on "breastfeeding" either, although I accept it's a term of convenience. I often get old ladies asking me, "Are you feeding her yourself?" and I want to say, "Yes - from my BREASTS!"
