The key really is mom. If mom is well grounded the daughter will be. Most daughters I know are little perfect copies of their moms.
I also recommend staying away from ballet classes and beauty pageants. No TV (get rid of it!) and focus on sports that are physical, like swimming, soccer and other ball sports. Pick their friends (while you can) accordingly. Later you also want to emphasize that the life plan is a college degree in a solid discipline that will feed a family and that we aren't going to rely on a guy paying the bills ...
