We read with interest the recent article by Langer-Gould and colleagues1 that analyzed the relapse risk of 29 mothers with MS who breastfed exclusively for at least 2 months (groups, 8, 5, 4, and 0-13 months) vs those who did not. A statistically significant reduction of the relapse risk in the breastfeeding group is described. The authors state that their small sample size was the main limitation of the study.
