You shouldn't put anything into a newborn or infant's ear canals. Neither cotton swabs nor wash cloths should be inserted into ear canals. You may gently clean the outer ear with a wash cloth using warm water or hydrogen peroxide. If you still notice more wax/cerumen, let your child's doctor take care of it. Younger babies having excessive wax is not a serious problem and every well visit to his or her pediatrician will allow the provider to deal with this problem.
