Brown Bag Break for parents The Children's Museum is for families, really. The Families First program, developed at Wheelock College and the Boston Children's Museum, is a set of lunchtime seminars for parents. Today's discussion is Temperamental Differences: Understanding and Accepting the Child You Have. As parents find out early, children are not the neat and tidy blending of two people's better genes. They are their own selves. This workshop helps parents understand their children's unique personalities and find aspects that enhance positive relationships within the family. Parents are invited to bring lunches, and child care is available during the sessions ($3 per kid). Noon-1 p.m., Children's Museum, 1500 Binz. To register call 522-1138 ext. 206. $10, $8 Museum members.
