Anyone may tovel keilim, including a small child or a gentile, however, a Jewish adult must be present to verify that it took place. The recitation of a brocha can only be done if a Jew does the immersion. Therefore, if many utensils are to be immersed with the help of a child or a gentile, the owner should first immerse a few vessels with a brocha and then the child/gentile can take over By Rabbi Moshe Heinemann http://www.star-k.org/cons-appr-tvilaskelim.htm
