Even funnier when little boys become teenagers (later men, some of them) and are reminded that they were breast fed by their best friend's mother. Enough material for a gross out teen movie.

Leica Mike, Sandton,

Why is everybody so concerned. Some mothers share other mothers partners and do it regularly ! If people had the opportunity to time travel back to the 16th century they would be horrified by the habits of the ordinary person. Never mind AID's (rubbish) in breast milk they did worse things.

My boyfriend horrified me when he told me that his mother breastfed a girl who was born the same time as him because her mother couldn't breastfeed. Formula milk was available but apparently it is common in Greece (hence Maria from Volos nasty comment) and he calls her his sister, shudder!

Sarah, Athens, Greece

I remember my grandmother telling me as a child that she always fed her husband's nieces and nephews, especially one family whose mother never had breastmilk. She said if she hadn't, they would have starved.

My concern now is disease. AIDS is now found in breast milk. What else is there?

You know as much about this subject and have as much that is valuable to say about this subject as I do about the experience of walking on the moon. Stick to stuff you can write something decent about.

I produced an excess of milk after my first child.

This was lucky as the mother with v large breasts in the next bed found it impossible to produce milk for her newly born baby.

I expressed my over-production, and her baby had bottled-breast milk from me.

That's milk-sharing. Old news.

Other animals do it, what's the big deal?

nursey, ipswich,

breastfeeding is awsome and natural i have breastfeed two of my 3 children i dont know if i would let some one else breastfeed my child but i always have exess breast milk wich i freeze ...unfortunatly because im on zoloft i cant donate my milk to the milk bank at king edward for the prem babies ..

Seems quite natural and normal to me, easier than running around buying a bottle and formula if a mother gets stuck and can't make it back for a feed she hasn't expressed for. I used to be a 'milk lady' collecting expressed milk for premature babies in hospital, a great way to help sick infants.

Some of the worst tyrants in history were turned over to a wet nurse, and see what happened. Of course some of the greatest and benevolent leaders in history were wet nursed, as well. So what does that prove except that it has been a practice for a few millennia. Now, about formula....

At what age would it be deemed appropriate to begin weaning them on Gatorade Miss Cassandra?

Marianella, San José, Costa Rica

Before the 2nd world war hit Malta it was common practice for families from the upper classes to hire women to breastfeed their babies. Apparently it's a question of histroy repeating itself...

Kevin Bonello, Marsascala, Malta

Good grief. Grow up. To debate this is about as stupid as arguing about whether women should be allowed to breast feed in public places. And from a woman who has never had a child?? She's not serious though.. she is just trying to be clever and funny...didn't work.

lecia sadler, Richmond,

I wasn't breast fed, and I turned out totally lacking in any self-esteem, manically depressed for my adult life and totally ill-at-ease with women!

Takes you pick: it's stats I guess.

But both of us are 'outliers' which go to prove the rule I suppose.....

Rhys Jaggar, Leeds, UK

If Sophie can find a safe means of losing some weight, that would be another option. I suggest that because I used know a woman whose back problems disappeared that way--but the weight loss was the result of stress over school and family causing her to get sick and not eat right.

Michael, Pueblo, Colorado, US

I well remember that about 50 years ago ,when I was about 6 ,my mother did not produce enough milk to breastfeed my youngest brother and I was sent twice a day to fetch a largish bottle of milk from a woman a few streets 'up the road' who had excess breastmilk .It seemed quite normal then.

If your friend is as modestly-sized as a 34D and has back pain, she's most likely wearing a badly-fitting bra. Get her to a shop like Bravissimo pronto! I'm a 34F and have never experienced back pain.

I will make this short, sharp and clear...YUK!

wendy, belfast, northern ireland

I was told of a mother who was very ill after giving birth after having my son , I was asked would donate breast milk for her baby ,as breast milk freezes well I was able to express and save some for her husband to collect (a bizzare doorstep meeting that one) I draw the line at sharing breasts.

Jacqueline, whitstable, KENT

Breast-sharing? Am I reading this correctly? Without starting a whole new debate, those who profess breast feeding to be a necessity need to re-evaluate their thinking.

Aber, Barrow-in-Furness, England

Breast-reduction surgery is a small tragedy in a dark world with few enough comforts as it is.
