Desosoft Cream should only be used on a baby if a doctor has carefully examined the skin and decided it's necessary. A 5-month-old's skin is very delicate, and using any medicated cream without proper medical advice can cause harm. Always consult a paediatrician first; they will assess the baby's condition and recommend treatment based on the specific medical need.

Your symptoms fit Atopic dermatitis, which often worsens in winter due to dry air. Keep the area well moisturized with a thick, fragrance-free cream (apply 2?3 times daily), use a gentle face wash instead of soap, and avoid hot water and harsh products. For itching or redness, a mild cream may be needed temporarily, and an antihistamine like Cetirizine can help reduce itching. If it becomes severe or doesn?t improve, consult a dermatologist for proper treatment.
