There’s this thing babies do. (Or, really, parents force their babies to do.)
It’s called “tummy time.”
For a few minutes, a couple of times each day, you lay your infant on her stomach so she has to practice holding her head up. That’s “tummy time.”
At first, my little, one week old baby could not hold her head up, at all.
So, we stopped doing tummy time. Tummy time sucks! For the birds! Who needs it.
