We've adopted a girl 6 months ago from Kazakhstan. She is 25months old now. She is a very happy and smart child and everything is normal for her. However, in the past few weeks, we notice that she has developed an unpleasant and sexual behavior. She kisses & hugs a doll and then puts the doll on the floor, then she sets on top of the doll and rubs her provide area against the doll. She seems to get pleasure from doing that. When we see that each time, we can divert her attention away. She is ok. However, when she is along, she does it again. We don't know what that is and don't know how to handle it. We are also very concerned but shamed to talk to other people or even doctor about that. Please let us know what we can and need to do at this moment. Thank you!
