Bellamy's should not branch out too much. They have so many untapped markets still. Taiwan, Indonesia, Middle East, India etc. They should roll out into those nations before they consider milk. Though their baby food is doing fantastic as well so potentially extending that is an option.
Even Chinese companies are trying to get into India. A2M would not do well there cause majority of Indian's aren't lactose intolerant. So selling a supposedly stomach product won't really take off.
