So my son, age 7, has been making noticeable comments and gestures showing that he has a crush on my SD, age 9. Nothing inappropriate has happened at the moment except for the awkwardness that we feel noticing it as parents and I think that SD is catching on. SD has a brother almost the same age so I do not think she is thinking of my son in the same way that he is thinking of her. I do think she likes the attention but is not quite sure how to react towards him. Question is, do I talk to my son about the fact that they are siblings now and that he can not behave that way to his new sister or do I leave it along and let it phase out on its own? I am afraid of making him act out more if I call him out on the situation, but I am concerned that things will get more awkward as time goes on OR worse. Has anyone else had this problem? What did you do?
