How do you make your kids fingernails grow longer?

To promote longer fingernail growth in kids, encourage a balanced diet rich in vitamins and minerals, particularly biotin, zinc, and protein. Ensure they stay hydrated, as proper hydration supports overall nail health. Additionally, regular nail care, such as gentle filing and keeping nails trimmed, can prevent breakage and encourage growth. Lastly, discourage habits like nail-biting, which can impede growth.
