This can be due to summers....please give a normal room temperature to child...not too hot ..not too cold...and this will heal by itself.

Rose water only on

Don't apply any packed oils, cream n soap. Just apply coconut oil very little n clean with water that's it. It will go away

Coconut oil is best

Jasmine aap ispe koi bhi oil soap na lgaye. Bas koi achi si moisturizer lagaye...Jaise ki johnson ka milk lotion ya aveeno lotion. Aur agar aaram nhi hota hai thoda bhi tou doctor se dikha dijiye.
