I teach a 4/5 year old preschool class and I have a female student who is exhibiting inappropriate behavior. She constantly talks about marrying another male student, boyfriends/girlfriends etc. It escalated a few weeks ago to her telling another student they were going to "play sex" with the male student. The other day she was pulling the front of her pants down during naptime across from another student so he would do it too. I know it is normal for children to be curious, but I am getting worried by this behavior. The mother is very concerned and upset by this and I'm trying to find any information I can give her to help. Thanks!
