sexual abuse or not

my 3 yr grand-daughter is staying with me at the moment. since her last visit she is touching herself all the time. She also rubs up and down on the coffee table legs says it feels good and that if she doesnt learn how to play the tickle game bubby wont play with her anymore and bubby rubs her and plays with her when mommy is at walmart or other places    should I be concerned about sexual abuse with my grand-daughter and also a 10 yr old touching and playing like this with a 3 yr old  also its a secret

ABSOLUTELY BE CONCERNED!  She has told you that she is being touched sexually. It would be normal for her to "discover" that certain things feel good from normal innocent self exploration. "Bubby" is doing something to her and you had better get it stopped before it is too late. Please investigate-today!

I would share this with her Mom because she is being molested by her brother. If Mom can not protect her, you will have to by reporting this to the child abuse hotline.

Oh GOD, PLEASE do something.  It's normal for children that age to touch and explore those parts on their own but obviously, her brother has been abusing her.  You need to hang on to her as long as possible until he's no longer able to do it.  Tell her mother, call social services, do SOMETHING.  REFUSE to let her be around him... I don't care if he's 10 or 28.   It's now your responsibility to make sure she isn't hurt anymore because her mother is probably going to have a hard time believing her son is molesting her daughter.  Believe me.  

I can't make my "PLEASE do something" big and bold enough to stress how much I mean it.
