Unusual Child behavior

When my daughter was 2, she started trying to put toys in her privates. I didn't know what was going on with her or if this was normal, so I took her to the doctors. I honestly feared someone had molested her. I spoke to her father about this and insisted he watch her and her brothers much more carefully. Not 2 weeks after the dr appt, my ex called me and informed me that his girlfriends son, Pooh (4), was caught with the neighbor girl, 3. The boy had the girls pants down and was using his fingers on her privates. Since then my daughter has been a typical girl, even though I have a secret worry that she was in fact traumatized by this. My worry wasn't based on anything she did, just a normal worry that in some way even though she was so young, she would be affected by that. Now, however, she's begun some unusual behavior. She'll be 7 in April. About a month ago, I found her and her 5 yr old brother behind the house hiding in some bushes. I don't really know what they were doing, but my son's pants were down and she was kneeling. I thought it was just natural curiosity. I discussed the situation with both of them, explaining how each had private parts, and not to let others touch or look at the parts. I informed my family, they're the babysitters, of this behavior and to pay attention for it. Since then, nothing odd has happened, which led me to believe it was a one time thing. Tonight however.... my mother called me. My girl drew a picture of my 5 yr old standing in front of a can. His penis and buttocks very prominent in the drawing. She labeled the picture with his name, also naming... Pee, and Poop, and Pee Can. She will have them in counseling by the end of the week. My daughter also has been grounded for Lord knows how long. I'm concerned, but at the same time kind of feel my mother is severely overreacting. But at the same time, I can't help but wonder if this is stemming from the whole "pooh" incidence. I don't want to blow this out of proportion and make it into something it isn't. I'm concerned this will fester into something more severe.

This isnt over reacting this is something to look into.... red flags go up in my mind ...
