In case you don’t get this week’s very New Yorkery comic, tummy time is when you take a baby and put them face down on the floor. Doctors tell you to do this so they can build up their neck muscles (and probably a bunch of other reasons). I thought it would be funny if I went in for a check up only to learn that I, a grown man, need more tummy time.
Yup, explaining the joke. Good times.
