Peeling nails could be a symptom of hand, foot and mouth disease
Peeling nails in toddlers can be caused by several factors, including trauma, infection, or an underlying condition. One possible cause of nail peeling is hand, foot, and mouth disease (HFMD). This disease typically affects children and causes fever and vesicles on the hands, feet, and mouth. While HFMD is usually mild and harmless, it can lead to nail changes, including peeling.
Onychomadesis is a condition where the nail plate separates from the nail bed due to a cessation of activity in the nail matrix, resulting in incomplete shedding of the nail. It can occur following an episode of hand, foot, and mouth disease, typically developing 28 to 56 days after the illness. The nails may appear peeled, with grey-white patches, and Beau lines, which are horizontal grooves across the nail plates. In some cases, the nails may shed completely or partially. This complication is usually self-limited and resolves without treatment, with normal nail growth resuming within one to four months.
Hand, foot, and mouth disease is most often caused by the Coxsackie virus or enterovirus 71, and it can lead to onychomadesis as a late complication. The virus affects the nail matrix, causing disruptions in the nail plate and proximal nail bed, resulting in the peeling appearance. While nail abnormalities during childhood are uncommon, they can be distressing for both children and parents.
It is important to note that nail disorders in toddlers and children are relatively uncommon. When they do occur, they can be associated with underlying systemic, cosmetic, or psychological conditions. Therefore, if your toddler's fingernails are peeling, it is essential to consult a healthcare professional for a thorough examination to rule out any potential underlying causes and receive appropriate treatment.
Additionally, it is worth mentioning that nail biting and thumb sucking are common habits among toddlers and children, which can be aggravating factors contributing to nail abnormalities. Proper nail care and hygiene practices should be encouraged to maintain healthy nails and prevent infections or other complications.

Nail biting and thumb sucking can cause nail damage
Peeling fingernails in toddlers can be caused by nail biting and thumb sucking. While nail biting and thumb sucking are common habits in children, they can have negative consequences on nail health.
Nail biting, also known as onychophagia, is often a psychological response to stress, anxiety, or boredom. It can lead to damaged teeth, infections, and teasing from peers. Additionally, swallowing bitten nails can introduce bacteria into the body, potentially causing stomach or intestinal infections. Although rare, long-term nail biting can cause damage to the nails.
Thumb sucking is a natural instinct in infants, providing comfort and a means of self-soothing. However, if continued for too long, it can lead to malocclusion or tooth misalignment, such as an open bite or overbite. Excessive thumb sucking can also cause nail damage and is a significant cause of koilonychia, or spoon nails, in toddlers. This condition results in abnormally concave nails that appear scooped out due to the pliable nature of the nail plate.
To prevent nail damage, it is important to address the underlying causes of nail biting and thumb sucking. Cognitive behavioral therapy (CBT) and acceptance and commitment therapy (ACT) can help individuals, particularly children, understand and manage the psychological aspects of these habits. Additionally, keeping nails trimmed and maintaining proper hand and nail hygiene can reduce the temptation to bite or suck.
In most cases, nail biting and thumb sucking are benign habits that children outgrow. However, if they persist or cause significant nail damage, it is advisable to seek professional help to address the behavioral and psychological aspects of these habits.

Beau's lines are nail depressions caused by trauma during birth
Beau's lines are horizontal ridges or grooves that appear as dents in the fingernails or toenails. They are nail depressions that are caused by trauma or damage to the nail matrix during birth, resulting in transiently reduced nail growth. Beau's lines are not a disease in themselves and are usually harmless, but they can indicate an underlying illness, injury, or skin condition that interrupted nail growth. In toddlers, they are typically caused by simple traumas that induce physiological alterations.
Beau's lines can be caused by a variety of factors, including dropping something heavy on the finger or toe, exposure to extreme cold, manicures or artificial nails, or slamming a finger in a door. Chronic conditions that interfere with blood flow to the nail matrix, such as hypothyroidism, peripheral artery disease, or Raynaud's phenomenon, can also lead to the formation of Beau's lines. Additionally, severe emotional stress, such as divorce, the death of a family member, or job loss, can be a contributing factor.
In terms of treatment, there is no direct cure for Beau's lines. However, addressing the underlying cause can prevent their recurrence once they have grown out. It is recommended to consult a healthcare provider to determine the cause and rule out any possible health conditions. The thickness and number of Beau's lines can provide clues about the underlying cause. For example, a single Beau's line on one nail may indicate an injury to that specific finger or toe, while lines on all nails can suggest an illness or stress as the trigger.
Nail disorders in toddlers are uncommon, with an incidence rate of 4.4% in pediatric patients according to a study in Turkey. These disorders can be associated with systemic, cosmetic, or psychological problems, and their management differs from that of adults. A thorough examination is necessary to rule out any underlying diseases, and understanding normal nail anatomy is crucial for diagnosing nail diseases.

Leukonychia is a trauma-induced condition causing milky white nail discolouration
Leukonychia, or leuconychia, is a medical term for the partial or full discolouration of the nail plate on one or more fingernails or toenails. The nail loses its general pink undertone and appears white. This condition is derived from the Greek words "leuko" (white) and "onyx" (nail). Leukonychia is usually not an alarming sign, but it can sometimes indicate severe systemic disorders or congenital conditions.
Leukonychia can be classified by its underlying pathology, distribution, or development. True leukonychia refers to discolouration due to abnormal nail plate keratinisation, while apparent leukonychia is secondary to disease of the nail bed. True leukonychia can be further subdivided into punctate and transverse types. Punctate leukonychia is typical of several fingernails and results from trauma to the distal matrix. Transverse leukonychia is rare in children and is usually restricted to the first toenails due to trauma from shoes.
The whitening of an entire nail is known as leukonychia totalis and is most likely to occur on all nails. It is caused by injury to the base of the nail (the matrix) and can be a clinical sign of hypoalbuminaemia (low albumin), which is associated with nephrotic syndrome, a form of kidney failure. Leukonychia totalis may also indicate liver failure, protein malabsorption, protein-losing enteropathies, or a genetic condition. In rare cases, it may be a side effect of taking sulphonamides, a family of antibiotics.
In children, nail biting, thumb sucking, and aggressive manicuring are common causes of leukonychia. Additionally, trauma from accidents involving doors or windows can contribute to this condition. While leukonychia is often benign, it is important to consult a healthcare professional to rule out any underlying diseases or conditions.

Onycholysis is the separation of the nail from the nail bed
Onycholysis is primarily caused by trauma, medications, or nail infections, but it can also be associated with autoimmune diseases. Injuries to the nail or the nail matrix, which is the area where nails start to grow, can cause onycholysis. Such injuries can be caused by bumping or hitting nails, wearing ill-fitting shoes, or prolonged exposure to water. Regular manicures, which involve forceful trimming, buffing, and polishing, can also lead to onycholysis. Additionally, chemicals found in nail products like nail polish, gloss, hardeners, and removers can contribute to the condition.
Fungal infections are another common cause of onycholysis. These infections occur when fungi enter through cracks or cuts in the fingers or toes, leading to thick, yellow nails with white spots and streaks. Certain medications, such as chemotherapy drugs, tetracycline, nonsteroidal anti-inflammatory drugs (NSAIDs), psoralens, and oral retinoids, can also induce onycholysis. Nail psoriasis, a condition that alters nail structure, may include onycholysis as one of its symptoms.
In toddlers, onycholysis can be the result of physiological alterations that induce inflammation of the nail matrix, reflecting superficial changes to the nail plate. This is often attributed to the fact that toddlers frequently play with their hands. Additionally, toddlers may experience onycholysis due to trauma caused by thumb-sucking or improperly fitting shoes.
The treatment for onycholysis depends on the underlying cause. For fungal onycholysis, oral antifungal drugs such as terbinafine, itraconazole, and fluconazole are commonly used. In some cases, cutting away the separated nail as it grows out may be sufficient. A conservative management approach and oral supplements can also aid the healing process. Applying lotions containing α-hydroxy acids after soaking the nails in water is another recommended treatment strategy.
