how to remove/prevent having rashes on the neck for my 1 month baby?

Rashes are usually cause by bacterial infection or irritation. Avoid prolonged contact to urine or stool, which means their diapers should be changed even before they get soaked in urine. The most common ointments given to get rid of diaper rash are Drapolene and Calmoseptine, But it's still best to consult your pedia on what's best for your baby's skin.
