RE: Ok... so... is breastmilk supposed to smell?
To me, it always had a sweet sorta smell (along the lines of condensed milk, but not quite), which I especially noticed on DS's lips after he finished nursing. In fact, I took to calling him "sweet lips" for the first few months because his face always had the same sweet smell after he'd finished nursing.
That said, and this may be more than you asked for, but nothing smelled worse for me than Breast milk that had been pumped, stored, served, and then left sitting around (my husband used to watch our son while he worked from home, bless his heart, but he wasn't always the quickest to rinse out the bottles afterwards!) I'd smell it as soon as I walked in the door from work, and would have to clean it up before I could go on and do anything else.
