In the US these specialty maternity nannies are known as Newborn Care Specialists (disassociating this specialty from medically qualified nursing). They are highly experienced in all aspects of newborns, aside from medical issues. They may work 24 hours a day, seven days per week, but most commonly work five nights/days a week for the first three months of a newborn’s life. The role can consist of assisting parents with feeding guidance, nursery set up, premature infant, multiples, colic, reflux, and sleep guidance/training. There are various training organizations that offer non-accredited certifications, however, in an unregulated field parent should ensure that the qualifications of their maternity nanny are legitimate and accredited.
