Although mothers with MS are at greater risk of relapse in the first 3 months post-delivery,1 those who exclusively breast-feed have a significantly reduced risk of such relapses.2 Currently, women are not recommended to continue immunomodulatory treatment during pregnancy or while breast-feeding,3 although recent studies do not indicate that such therapies are associated with prenatal developmental toxicity.4Fatigue is a common, debilitating symptom of MS, therefore expressing breast milk has certain advantages: it mimics exclusive breast-feeding while enabling others to help with feeds when the mother is tired. The mothers’ MS specialist team can provide information and advice on comfortable positioning and other practical issues, and it is important to involve them if the mother who wishes to breast-feed has any MS-associated limitations. Baby slings may also be useful, to help support infants while they are feeding.
