fedup - yes, you can take WHO and UNICEF as meaning the same thing in this case, as the Baby Friendly initiative is linked with the WHO work on supporting breastfeeding, though I hope you have misremebered anyone talking about 'regulations'.
You say that the argument about 'timing' doesn't hold water because 'all the stuff' at antenatal class has the same time delay on it. This is simply not true. The information given in an antenatal class is not normally a list of instructions to remember accurately, or else....so the proscription on bottle demos being at the wrong time is not the same as anything else that goes on in an antenatal class.
Much antenatal class information is about pregnancy anyway - what's happening to you now - and in NCT classes at least, focus is on confidence building throughout the course as much as anything else. The odd thing that does need instructional guidance such as massage techniques or different positions or relaxation is practised actively by the participants, and many, many times....otherwise it just doesn't go in!
I sort of agree with you about Actimel and Aptamil - I think it's rare that a mother, however sleep-deprived, would think those little pots are infant formula milk, but I have heard of two instances where the mother's partner, sent out for Aptamil, brought back the wrong stuff, and one case where a mother with learning disabilities actually did try to give her baby the Actimel. I don't think the antenatal class routinely trotting out a brand name with a 'get the right stuff!' message is the answer to this very rare situation, though. Better postnatal care might help here.
I think, like you, any bottle feeding mother should be helped with a demo and a practice before she goes back home - it should be one to one, and there could be a follow up in her own kitchen if appropriate. Why will this not happen? It's a simple and sensible and not very time consuming way of ensuring safer feeding.
Not doing a group demo in an antenatal class is not 'suppressing information' about formula feeding. In fact, I would like fuller information about formula feeding to be available at all times - people need to know the hazards of using it, they need to know the differences in the formulations, they need to know its potential impact on breastfeeding, and they need to know how little credence they can give to vague slogans, and they need to know that 'Carelines' run by the manufacturers are another tool of marketing.
I don't feel especially strongly myself about Boots' silly little notice, except I don't believe they are 'sorry' they can't offer a discount (see my previous post about the fact they could!).
