Most of the causes of nail delamination in infants are low water content and excessive dryness. In a few cases, the child is undernourished and the growth of the nail plate is slowed down; in individual cases, this is due to systemic or genetic diseases, etc. If the nail is delaminated but the child is eating, urinating, defecating and growing normally, then there is no need to worry, as it is important to apply moisturiser, trim the nail plate that has been separated and correct the bad habit of eating fingers.
