Could you tell me what to do for my son's teething besides oral gel and tylenol, (acetaminophen) pleaseeeeee?

Let him chew: Chewing on something cold and firm is helpful. One idea is to give them a damp washcloth that as been frozen in the freezer to chew on. Commercial teeth rings that can be frozen are available as well. Teething is a normal process. I would avoid medication like painkillers unless absolutely necessary. Most babies really don't need them.
