There’s a red patch on the back of head of my 3 month old baby , just above the neck . She keeps scratching it , and it’s not going anywhere . Is it normal?

A. Okay so apply calamine lotion that would be a good option for you maybe it is associated with heat so clean it with water properly after that you can apply this lotion every 3 to 4 hours which will help in soothing the skin of the child
