Because for health reasons breast milk is the best source of nutrition for a baby.
Yes formula isn’t poison, but it is a substitute for breast milk.
Marketing laws do not allow for formula to be advertised because by doing so it is promoting a substandard source of nutrition for babies (not my words) meaning babies do not receive what is considered to be the best source of nutrition - breast milk.
In the same way that adverts for seeets and McDonald’s etc are no longer shown on TV, because they can’t advertise food that comes with possible health problems, or, as in the case of formula, be advertising the use of a product that takes away the health benefits of other sources of nutrition, like breast milk.
FWIW, I work in infant feeding and although I don’t promote the use of formula I will ALWAYS give support and information to any mothers who are bottle feeding. I am classed as an Infant Feeding Specialist and that to me means I am there to support mothers regardless of which method they choose to feed their baby. If I was only there to support breast feeding mothers then I would be called a breast feeding specialist.
On the unit where I work I can safely say that although we support and assist with breastfeeding we are also happy to support and give information to mothers regarding formula too.
There is a big difference between promoting formula and providing information about formula feeding on and I do not think there is anything wrong with the latter and it saddens me to think that some women don’t receive this guidance and advice from the HCPs.
