What is the normal schedule for a confinement nanny? Having one for the first time and am unsure of what she's supposed to help with. Do you ask her to buy the confinement related things like herbs etc?

Confinement nannies are supposed to look after both mother and baby, so night duties are supposed to be covered by her. She can take naps when the baby is asleep. Marketing is "supposed" to be done by your family but can be done by her for an extra fee.
