Why does a 15-month-old baby bite their nails?

Nail-biting in 15-month-olds usually comes from a few reasons:
The most common cause is exploration and the need for oral-area stimulation. At this age, babies continue to explore the world through their mouths, and fingernails are part of that exploration. During teething, they may bite their nails to relieve gum pressure.
Second, nail-biting might be a temporary stress-relief or self-soothing method. New environments, separation anxiety, or tiredness can drive babies toward this habit.
Third, it may have simply become a habit — once started, they repeat it without noticing.
At this age, it's rarely a sign of a serious problem. The most effective thing you can do as a parent is redirect their attention when you see them biting nails (for example, offer a toy or book) and keep their nails short and clean. Harsh scolding or punishment usually doesn't help and may reinforce the behavior.
If nail-biting is severe, causing bleeding, or continues after age 3, consult your pediatrician.
