Nobody likes to see a baby in pain. But it's been surprisingly hard for doctors to figure out how to make shots and other medical procedures hurt less.
The solution might be as simple as giving a baby a bit of sugar water before the shot. Or it might not be so simple at all.
How do we know when a baby's hurting? A parent might be able to tell the difference between a cry of pain, the wet diaper cry, and the boy I'm tired cry. Doctors and nurses lack that intimate knowledge.
