J. - I just finished helping my un-married daughter finish under graduate school and using savings put away, bought her first car. I recommend you start with spending some special mom/daughter time with you and them only, focusing on more quality and personal level experiences and positive conditioning rewards. This may be your only intervention opportunity before "boyfriend" takes over her mind. Find out what she likes most, ask her if she has a five year goal. Because she is becoming a young woman, place her in a non-threatening environments that most girls like, which empowers her as a young woman, such as horseback riding, hobbies, martial arts and especially sports. Slowly they may rollover extra energy into something more positive and personally challenging and enjoyable then puppy love...because after the litter arrives, there is not going to be time to go back and rewind to it over again.
