A. Lactogen is good that you can use because all the other brands apart from this one you are mentioning a very expensive actually so you can go for this one this is of course not very cheap it is but it is still budget friendly so give it for six months complete after that you switch to time pasteurised packet milk that would be much pocket friendly and affordable
