My 5yo girl is constantly talking about boyfriends, getting married and kissing boys. She changes her "crushes" regularly but does get very shy and giggly over whoever she is currently fond of. She constantly talks about kissing and it is beginning to concern me. I am a single mother and have lead a celibate life since she was born. I monitor her TV closely, but ads in prime child viewing do show lots of kissing. Is it normal for girls to talk about boys and kissing at this young age?
