In this time of COVID-19 threat, we want breastfeeding to work for our babies so that their immune system remains as strong as possible. We want breastfeeding to work for women so that life is as easy as it can possibly be in the midst of everything. Fussing and crying at the breast is miserable for both mother and baby - and can usually be prevented or repaired. Emma McCabe, a breastfeeding counsellor in Brooklyn, New York, and Dr Pamela Douglas, an Australian GP-lactation consultant and breastfeeding medicine specialist, discuss three main causes of unsettled baby behaviour with breastfeeds. Dr Pam is founder of the evidence-based Neuroprotective Developmental Care (or 'Possums') programs and author of The discontented little baby book: all you need to know about feeds, sleep, and crying.
