I had this just happen with my daughter's half sibling who is 7 and she is 3 and a half. I am currently struggling with how to deal with it. Will she remember this later in life? How do I put my complete trust in her father and I who are not together to stop this from happening again? Do I get her help or is that just making her relive the incident so that she does remember? When she brought it up to me, she was not traumatized, and was just very matter of fact like it was no big deal. I know she has no idea, but I don't want her to get older and to realize what you are just realizing now.
Also, I am petrified that when she goes to her dad's house next, that this may happen again. Ugh.
you shold not feel gui;ty about this, i remember playing simular sex imitation games with my bro and friends. theres no shame in it, its just how kids learn, they copy everything. let it go, honestly, dont let such a silly thing affect your adult life. all the best to you x
Sounds like you saw something when you were a little guy . . . and what you did was the little kid version. No big deal. Sounds like no harm was done to either your sister or you. Let this go----------- but I will say that you should have your depression treated. That can make all matters in your life worse and dealing with the depression helps keep all things in perspective. good luck
Also forgot to mention that I've had no indication to suggest my sister remembers the incident and we have grown up with a normal sibling relationship.
