Why is my baby's finger peeling?

Peeling skin on a baby's fingers can have multiple causes: 1. Bad habits: Some babies have the habit of biting their nails, and long-term nail biting can cause mechanical damage to the local skin, leading to peeling. 2. Deficiency of trace elements: Imbalanced nutrient intake in babies, such as deficiencies in vitamin A, vitamin B, zinc, calcium, and other trace elements, may lead to dry and peeling skin. 3. Contact peeling: A baby's skin is delicate, and prolonged contact with rough or irritating surfaces may damage the skin and cause peeling. 4. Tinea manuum (hand fungus): If parents have fungal infections such as athlete's foot or hand癣, frequent contact with the baby or sharing personal items may transmit the fungus to the baby, causing hand fungus and resulting in skin peeling. 5. Dyshidrotic eczema (pompholyx): Factors such as emotional stress, sympathetic nerve excitement, or skin allergies may induce dyshidrotic eczema, and skin peeling may occur after the blisters dry up. The specific cause needs to be determined based on the baby's symptoms and a doctor's diagnosis. If the peeling on the baby's fingers is severe or persistent, prompt medical attention is recommended.
