Babies are infrequent blinkers: The jury is still out on exactly
why human babies blink far less frequently than adults, usually just twice or less over the course of a minute. Additionally, a study found that children blink more frequently as they grow older, not reaching full “blink maturity” until the age of 14 or 15. One theory about why babies blink less is that they sleep so much and thus don’t need to lubricate their eyes as frequently as adults do. Another theory claims that infants, when awake, are busy working their eyes (but not their eyelids) overtime to soak in visual information.
