I noticed that my 6 month old has a few white dots on his nails...it looks like it's on the nail bed rather than the nail itself.they are about 1 mm circles, and only one per nail, on a few nails. what is causing this?

White spots on nails: It is harmless and most commonly caused by minor injuries that occur while the nail is growing. It is not a sign of excess or deficiency of calcium and zinc or other vitamins in the diet. Very common in babies. White spots disappear after around eight weeks, which is the amount of time necessary for nails to regrow completely. The pattern and number of spots may change as the nail grows.

White nail spots: white spots on nails can come from a variety of conditions including vitamin deficiency, mineral deficiency, fungus, trauma or just a normal variant. Have your child examined by a Podiatrist who treats children.

Minor irritations: Minor irritations, injuries, eczema affecting the cuticles. Ignore them. Relax.
