ThereĀ is one patch of floor in our apartment that will, from this point forward, be cleaner and wetter than anywhere else. You have started your tenure as a swiffer sweeper substitute by getting your tummy time on the actual floor. The drool contributes to the moisture profile.
“Tummy” time is a slight misnomer; it should be “knees, hands, feet, back, face and sometimes-tummy” time.
