Post-natal refers to the period after childbirth, and synonyms for this term can include words such as postpartum, after-birth, puerperium, and maternity. While all these terms refer to the same period, they may have slightly different connotations or denotations depending on the context. For instance, postpartum tends to focus more on the physical and emotional changes that occur after birth for both mother and baby, while after-birth may be more narrowly defined as the time immediately after the baby is delivered. Puerperium refers to the six-week period after childbirth, whereas maternity can encompass the entire experience of being a new mother, from pregnancy to post-natal care.
