My 18-month-old bites their nails. I wanted your thoughts before seeing the doctor.

Nail biting at this age worries many parents, but it's actually not uncommon at 18 months. Usually it's curiosity, mimicry, or a temporary way to self-soothe—not a serious issue.
First, ask: when did it start? Has something big changed—sleep schedule, caregiver, home environment? Sometimes a new source of stress brings it on, and sometimes your baby is just discovering their nails and testing them out—and it passes on its own.
What can help: when you spot it, gently redirect—"Let's play with this toy instead of your finger." Criticism, scolding, or "don't do that" often backfire and actually reinforce the habit. Keep nails trimmed short to minimize any accidental damage.
If it doesn't ease up in 2-3 weeks or is intense/frequent without any clear trigger (like stress), worth mentioning to your pediatrician—there might be underlying stress or sensory need worth exploring.
