I’ve always wondered this- and I never got a straight answer because nobody ever too me seriously about it :mad: .
In movies, and urban legends, it seems like someone who accidentally drinks breastmilk spits it out in alarm as though it were poison or something. I think this is silly- If anything, I would imagine it would be more nutritious for people than cow milk.
There is no reason why anyone who can drink cows’ milk cannot drink human breastmilk. Human milk happens to be much higher in lactose (milk sugar) than cows’ milk, and the majority of the world’s adults are lactose intolerant, and therefore should avoid any milk.
Another key part of that standard “But that’s my breastmilk!” spit-take is that the unwitting drinker doesn’t know until someone speaks up. Not real likely. All that lactose makes breastmilk taste sweeeeeet. (Ever wonder why little kids have such a sweet tooth? Maybe it’s because nature made them crave all that yummy sweet mommy juice.) It also contains much less protein than cows’ milk, which makes it feel “thinner” somehow though the fat content is about the same as whole milk. I’d expect that if your mouth is all set for cows’ milk, the experience of drinking breastmilk instead would be an unpleasant surprise.
For what it’s worth, the joke falls flat in Norway, where nearly every mother breastfeeds her infant. So the taboo is not universal.
I was shopping in Sainsbury’s once and I had to do a double-take at a row of milk cartons on the shelf; I could have sworn they were labelled ‘Breast Milk’.
On closer examination, it turned out to be ‘Breakfast Milk’ (same as ‘gold top’ - extra creamy milk from Jersey cows.
[TMI ALERT]In my usual spirit of wanting to taste new things, I asked my wife if she would let me try human milk; she consented, but sadly she had big problems breastfeeding our kids in both cases so it just wasn’t possible (and I don’t fancy anyone else’s)[/tmi]
There isn’t any fundamental reason I know of – it’s probably a cultural taboo. But kids have been breast-fed until they were surprisingly old. (See Bernardo Bertolucci’s movie The Last Emperor, which caused a mild sensation when it came out. I’ve heard of other cases.)
Look up “Roman Charity” on your search engine.
And you have to mention Piers Anthony’s short story “In the Barn” (it’s in one of the Dangerous Visions anthologies, as well as in one of Anthony’s own short story collections) about a parallel Earth in which some humans are specially bred as “milkers”. People there can’t stomach the idea of drinking milk from cows.
It is taboo because it is not normal. Other than feeding an infant in American culture, sucking on breasts has sexual connotations. Once the child is beyond the age that your average child drinks from a bottle, breast feeding comes across as incestuous or as child abuse, although not that severe. But that is why it is taboo, because it is not the norm and has sexual connotations.
