Food that is made to be used instead of breast milk is known as infant formula. There are many laws that regulate how infant formula products should be marketed. Nestlé's soluble milk is a product that falls under this definition. In the 1970s, Nestlé marketed its soluble milk to mothers with infants. This was also done in developing countries. The marketing campaign led to a boycott known as Nestlé boycott, which is still ongoing. In 1981, the World Health Organisation published a guideline for advertising infant formula products. Nestlé is being critizised because supposedly it does not respect this code of conduct. Nestlé's policy states that breast-milk is the best food for infants, and that women who cannot or choose not to breast feed need an alternative to ensure that their babies are getting the nutrition they need. The problem is that mothers who stop breastfeeding will not be able to start again, after some time. They will become dependent on infant formula products to feed their babies.
