I've spent enough time watching women breastfeed over the past 3 years to know that unless you are very lucky, the baby requires almost constant attention to make sure they are still latched on, adjusting your and their position, burping them, etc etc. The idea that you can do that with full concentration in a working environment is laughable.
As a modern, reconstructed dad I spend a lot of time around mummies. Oh yes.
The hilarious thing is when they give you an accusing look because they think you're trying to sneak a peak at their tit , utterly oblivious to the fact that a breastfeeding mum - however attractive - is about as sexually alluring as, well, Diane Abbott.
