How do I clean my newborn baby's ears with mustard oil?

It is advisable not to go with any oiling methods to clean your baby's ear unless its prescribed by a doctor. Mild to moderate earwax build-up is common in babies. I usually wet a soft washcloth in warm water and use it to clean the earwax that's collected around my baby's outer ear. Also, don't push the cloth inside the ear. Most of the time, any earwax that is visible will fall out on it’s own. Ears have the ability to dump off the earwax accumulated within the duct and this process usually takes place when we sleep. So there is no need of pouring oil to dissolve the earwax.
