my baby always wear soft wollen cloth and not tight near the neck. rahes only around half neck and i am applying himalaya rash creme but did not work.

Is that area red. If so may be they are rashes. You can apply mamaearth diaper rashfree cream. It is good for other than diaper rashes also. Apply it 2-3 times a day. It will reduce the itching and redness. I am also using it for my daughter. And dont use a rough cloth to clean baby. Use wipes. I am using mamaearth bamboo based wipes.

Sandhaya What kind of clothes you wear for her? Is it too tight near the neck? Like woollen sweaters etc. Change the lotion, soap brand and see. You can also buy calamine lotion and apply.
