"Swimming infants" might have been convenient, or they might not.
(I'll have to use my time machine to go back 4-5 Myr to ask the
mothers - I suspect the answer would be a definite "No".) Its
implications for the AAT case are insignificant.

The first bipedal infants spent most of their time in the same way
as modern h.s. infants spend theirs - in a safe place on their backs
- in a crib of straw in the rocks. Once they started to crawl, an
inability to swim would have been a real advantage to the mother.
They would have stayed put on the rock where they had been placed.
