Suddenly, the husband sent me this link: http://health.msn.com/health-topics/articlepage.aspx?cp-documentid=100253798&GT1=31036. He said that I need to read the “twirling cotton-tipped swabs in the ears” since this is my favorite thing to do with the baby. He requested that I will not damage the ear of bb. Hmmm, why will I do that? Anyway, I thanked him for this article since it is nice and so informative.
