BABY BOOM

With husband Mark Harmon coaching breathing during delivery, actress Pam Dawber gave birth to a boy Monday. Sean Thomas Harmon weighed 8 pounds, 14 ounces and measured 22 inches long, a spokesman for Dawber said Tuesday. The spokesman said he would not name the Los Angeles-area hospital because of the couple’s desire for privacy. It is the first child for Harmon, 36, and Dawber, 35, who were married March 21, 1987.
