"Service women who wish to breast-feed their child should bear in mind that on their return to duty they are liable to undertake their full range of duties . Local circumstances may permit a return to duty whilst still breast-feeding, however, service women have no right to this and will be expected to go on exercise, take part in operational deployments, be drafted to seas service (if so liable), and undertake unaccompanied or emergency tours. It is, of course, up to the individual service woman to decide whether to breast-feed, and, if so, when to stop. The Department of Health currently recommends four to six months for exclusive breast-feeding. After that there is 'little benefit'. However, service women who wish to be certain of being able to breast-feed beyond their eighteen weeks' OML period should take advantage of OMA [occupational maternity absence] to cover this period."
" ... the scientific evidence indicates that the longer a woman continues breast-feeding ... the greater the ongoing health benefits for her and her baby, at least until her baby is twelve months old."
