Low milk supply while sick: what to know

A fever, pain, congestion, vomiting, or exhaustion can make feeds less frequent or less comfortable. Some medicines are suitable during breastfeeding and others need a check, so tell the prescriber that you are feeding. A common cold does not automatically require stopping breastfeeding; the infection and medication both need individual consideration. If you are separated from your baby, expressing can help maintain stimulation when you are able.

Rest whenever someone else can safely handle household tasks, keep water and easy food nearby, and offer feeds according to your baby’s cues. Wash hands before touching your baby or expressing, and ask a clinician or pharmacist to check any medicine. If latch or output changes, a [Lactation Consultation](/treatments/pregnancy-and-birth-care/lactation-consultation/) can review positioning, milk transfer, and a temporary feeding plan.

Contact a clinician promptly if you cannot keep fluids down, feel faint, have a persistent high temperature, or have a hot, painful breast with worsening redness. Get urgent help for breathing difficulty, confusion, severe weakness, or signs of dehydration. Your baby needs prompt assessment for unusually few wet nappies, difficulty waking, repeated vomiting, breathing problems, or inability to feed.

Is my illness or medicine compatible with breastfeeding? How can we protect my baby’s intake while I recover? What symptoms would mean I should be assessed today?
