While the baby is sleeping, pick 1: sleep, pump, exercise, cook (if it can be done quietly), eat, write, errands (if dad is not in a meeting), make phone calls, catch up on life in general (jk – that’s impossible).
While the baby is awake, pick 1: eat, get dressed, go to the bathroom, put the dishes away, cook (only if the baby is in a good mood)
Weekends, pick 2 (3, if we get lucky): walk to the park, exercise, assemble baby’s newest toy, put away stuff baby has outgrown, laundry, meal prep, clean / organize the house.
