Treatment with a DMT for CIS or MS during pregnancy and/or first weeks post-partum, with the exception of formulations of interferon-beta, glatiramer acetate or pulsed corticosteroids
Treatment with drugs known to transfer to the breastmilk and with established or potential deleterious effects for the infant
Treatment with any investigational agent within 6 months or five half-lives of the investigational drug prior to the LMP
Exclusion Criteria related to the Infant

Any abnormality that may interfere with breastfeeding or milk absorption
Active infection (may be included once the infection resolves)
At least one documented brief resolved unexplained event (BRUE), as defined by the 2016 Guidelines of the American Academy of Pediatrics
