Peeling nails in infants can occur without any cause for concern and is more common than most people realise. The nails are thin and may shed for no obvious reason or more often after a common childhood illness such a bad cold, urinary infection or viral illness with a rash, especially if the child has had a temperature. This non-specific cause for nail shedding is presumed to relate to a temporary interruption to normal nail growth and development. In this situation nothing needs to be done and the underlying nail grows back normally. There is a virus causing hand foot and mouth disease which can cause nail shedding as part of the acute symptoms as well as mouth ulcers and a typical rash affecting the hands and feet. The other more specific infection is fungal but this tends to affect only one or two nails and seen as a slowly progressive yellowish discolouration and thickening of the nail, rather than peeling. Nails are a reflection of the child’s general health and a more longstanding problem of the nails may rarely be an indicator of an underlying medical condition such as anaemia (usually iron deficiency), a thyroid problem or other metabolic or genetic condition. A specific rare genetic condition which includes abnormalities of the nails is ectodermal dysplasia. To summarize in most cases absolutely no cause for concern, but if the problem persists you should see your GP for advice.
