Recently, my 3 yr old started trying to kiss me on the lips (even though we already had established that we give 1 kiss on the cheek at a time) and nibbling/licking ears of others in the family. I would explain that this behavior is inappropriate and tell him not to do it. However, it has come to my attention that my older teen daughter had been making out with her boyfriend in front of my other children (ages 13,14, and 3). We have always had strict rules about boys being in the house while we were out and were sure to have someone (us or the younger siblings) in the living room with them at all times to avoid this type of behavior, but the others never told us what was going on. I asked again last night who taught my 3 yr old to lick ears and my 13 yr old admitted his sister and boyfriend were doing this in front of them. Is this considered sexual abuse? My daughter is now 18 (since mid August) and is currently living with her grandparents to help them with their horses, but I am concerned about the effects this has on her younger brothers, especially the 3 yr old. How do I handle this with all of them and do I question the older boys on why they didn't tell me when it was happening? I am disgusted that she would openly engage in this activity in front of them and almost feel that she has violated them by doing so.
