postpartum recovery; convalescence after childbirth
Refers to the period and process of a mother's physical recovery after giving birth. Often used in contexts of maternal health and traditional postnatal care.

産後 means 'postpartum' or 'after childbirth' in general, while 産後の肥立ち specifically refers to the recovery process and condition of the mother.
The phrase combines 産後 (postpartum) with 肥立ち (growth, recovery, convalescence). 肥立ち comes from the verb 肥立つ (ひだつ), meaning to recover strength or thrive. The exact historical derivation is uncertain, but the expression is traditionally used in the context of maternal health.
