No, it is not required to clean the earwax daily. Earwax is very normal and in fact is antibacterial. Just keep the outer surface of the ears clean using a soft cotton cloth. Do not use any pointed and sharp objects to clean the ears. It is advisable to not use earbuds as well. Ear drops can be used after a prescription from your child's doctor if there is excessive build up of earwax in your child's ear.
