No, not too young at all. I can't remember the age my son started but it was younger than 8. I would definately choose one that does not contain aluminum, safer for everyone but especially kids. (Except the one I use for myself does have aluminum.) Watch the wording: some have aluminum but don't use the actual 'word' aluminum in the active ingredients; such as GLY, GLY anhydrous, zirconium trichlorohydrex, zirconium pentachlorohydrex. Suave Men and Arm & Hammer are two I can think of right off the top of my head.
