my daughter ia 2 months old. should i wash her head daily or not ???

Daily and in this weather is not good may be twice a week you can wash and oil her hair well before wash is better.

but i lives in kerala.Nd herr is very hot

ohh then you can do it alternate days no problem. anyways in south India it is a practice you can do no worries

You do not need to wash the hair daily. If you feel that the hair is sticky due to milk spitting etc then you can wash with warm water.

agar Modeling krnay k liyay Jana hai baby ko..
then wash daily..

if not,
wash twice a week.
B'oz it might harm her..

u can bathe daily or alternatively depends on the Weather leaving Head.
