My newborn of 2 months has a strong sour smell in his right ear. I am almost positive it is wax buildup as my husband has this issue and has to his ears unclogged twice a year. He mentioned the smell is the same. How do you suggest getting rid of the smell if his ears are not at a point that the doctor is willing to clean them? Are there any natural at home remedies that are doctor approved to keep this issue under control? Thank you!
