Impurity after childbirth
Impurity after childbirth is the concept in many cultures and religions that a new mother is in a state of uncleanliness for a period of time after childbirth, requiring ritual purification. Practices vary, but typically there are limits around what she can touch, who she can interact with, where she can go, and what tasks she can do.
