The tot's already got an entourage! Grandmother Lynne Spears and bodyguard Perry Taylor (a.k.a. "The Manny") are on call whenever Britney needs a helping hand. Taylor, a U.S. Naval Academy grad, is frequently spotted out with the family – but he's not a nanny. "He's protecting Britney and he's protecting the child," a close source tells PEOPLE.
