I think it would be best to see a professional - at least run it past your pediatrician. My experence has shown this kind of play between siblings to be more harmful than this kind of play with friends.
All the best.
Thank you for your post. I will be keeping a more watchful eye. There are some suggestive video games played by their friends. I know my 13 yr. old has played them when visiting. Also if this is allowed they may monitor other media less then myself. We always reinforce our believes before a visit, and ask questions after, ie. (No internet without total supervision. and What did you do at your friends?) I do not wish to judge others paranting choises. However I do strongly believe children are to "worldly" these days. This has showed me some things I need to improve on as a parent. Also to continue taking things in stride. Your post eased my concerns. It reminded me that I know myself and my children. Thanks for that. hall95
You handled this situation well, the taking especially the 13 year old was good, it would still be a wise thing to check their friends, and supervise them when you can, could they have seen some inappropiate material at other childrens homes,perhaps at sleepovers or in friends homesw, you are not in control of what others allow their children to see or do.I do think that this play is very common and certainly sems to ve a part of childhood, so keep it in perspective on the worrying about it side. Keep being aware and let it go now.
