Patients who can't tell you what's wrong. And parents.
"Tiny human" is real affectionate nurse shorthand — adult patients can point to where it hurts; a two-year-old just screams and hopes you figure it out. Reading a tantrum, a cry, or a flailing limb accurately enough to actually treat it is its own specialized skill.
Not about being rough with kids — the opposite. It's a quiet brag about being fluent in a language most adults never learn: toddler.
For the peds, NICU, or school nurse who's negotiated a flu shot down to "just the arm, not both arms" and won. The retro look also makes it an easy pick for someone who wants their shirt to look a little more considered than a bold-text joke tee.
