There are plenty of options for the younger set this month, including Little Women, the Musical, based on the Louisa May Alcott story (Kennedy Center Opera House, June 28-July 23); another little woman, a red-headed moppet named Annie (Wolf Trap, June 27-July 2), and an even littler woman, Barbie Live in Fairytopia, which brings the perennial best-selling doll to life (Warner Theatre, June 21-25).
