Mother-care protected dependent infants and removed the sharp survivorship kink near stage 2. Mother-care alone increased expected post-reproduction time but did not produce extensive PRLS by post-reproductive representation. Adding mother-care to PRLS-enabling combinations eliminated extensive PRLS because mothers outcompeted grandmothers as caregivers. In the model, mother-care reduced the death rate of dependent infants tenfold when their mother was present. Mother-care proposes that females gain fitness by helping dependent offspring survive after the last birth.
