Be available when girls are ready to talk. This is usually when it's most inconvenient for the parents. Encourage daughters to think clearly for themselves. Respect and praise their talk. When teenagers temporarily lose their heads, don't panic.
Panicky parents make things worse.
Calm parents hear more. Also, let your daughters know that as a parent you are strong enough to deal with their problems. Parents shouldn't take things too personally. Rejection, moodiness, irritation are normal for adolescent girls. Try to have a sense of humor.
