If it's only affected one or two nails, it could be infection. However if all of his nails are peeling, he may have some skin problems. You may want to take him to a doctor.
They could be defficient with a particular type of protein, found in things like Jello. Don't worry unless it worsens or doesn't resolve itself in 10-15 days.
There is little reason to be concerned. Peeling nails are usually caused by frequent exposure to water. If it lasts more than a month, consult your child's doctor.
There is no need to panic, however I would definitely make an appointment with your toddlers Pediatrician. Nails that peel can be a sign of a vitamin deficiency.
no i dont think so bet if you toddler has been sick then that is a possibility why they may be peeling. when a child is sick the nail bed stops growing. when they ar eover the sickness the n then the nail will grow back so no you shoulnt worrie.
