If you have a child, there's a high chance you will recognise this rash. It is common for babies under the age of 6 months to develop a rash in the crease of their neck. The rash may appear red, spotty, look sore and or moist There are several reasons a rash may occur including: * Fungal infection * ⁠Heat or sweat retention * Irritation from cloth * Milk or drool having prolonged contact with the skin, causing irritation. It's more prevalent in younger babies because their necks aren't strong enough to hold up properly, causing moisture to become trapped in the neck folds resulting in irritation and providing a perfect warm breeding ground for infection. You can try to prevent neck rash by ensuring the neck is completely dry after bathing, gently pat dry the neck after each feed Most common neck rashes will disappear on their own after a few days of keeping the area clean and dry. Keeping baby cool and dressing them in light, 100% cotton fabrics. If the rash gets worse, skin starts to weep, bleed or split, contact your dermatologist . We usually advise simple barrier cream to apply to the neck or in the event of an infection, cream to clear it up. By the time a baby is sitting up and fully able to hold their head up, neck rash usually disappears.
