TRIGGER WARNING- sexual abuse

[mortifyingmouse]

I've NC for this. I don't know how to feel or what to think. My mind is completely fried.

Basically MIL rang me today about an incident which happened yesterday while we were visiting SIL's house.
My DS 7 has been accused of touching and licking his younger cousin's 'girl parts' (she's 3). After a lot of denying from DS he finally admitted to it. I feel sick! I'm mortified, and I feel like such a horrible mum!
DS told he helped her change her underwear after she went to the toilet and touched it as he was helping her pull her pants up. The licking he said he didn't know why he did but admitted her licked the very top of her leg right near her privates. Said cousin told him to stop which he did and carried on playing with the toy kitchen.

DS admitted what he did to his other cousin (the older sister) they didn't understand that it's wrong. She then spoke up and told her mum.

I'm worried and I've spoken to both DC to make sure that they have never been touched or anything as I'm unsure as to where he got the idea to do this from.

I have had a very serious word with DS, I don't know how to handle the situation. DP is away but returns tomorrow so he said he will speak to DS too. I've told DS how very wrong and serious it is doing what he done. I'm not defending him but I know he didn't do it in a malicious, sexual way. He knows nothing to my knowledge about anything like this. He's 7 years old!

So AIBU to be feeling like such a failure as a mum? Have I done something wrong? This is my little boy and I can barely look at him right now, I'm just ashamed of him at the moment in time.

Thank you for the messages. Just to clear something up, DS didn't take his cousin to the bathroom intending to do what he did. They were alone playing with the toys and the cousin went to the toilet. She then came back and wanted to change her pants, DS helped her to pull them up.
He has been banned from his switch and I'll certainly be watching like a hawk whenever I allow him to again.
I will be contacting the NSPCC for advice.
I've spoken to MIL and the cousin is ok. We are staying away for a bit as I think that's best for now. I am trying to get to the bottom of where this action came from as obviously it's a serious thing. DS is quite remorseful too as I couldn't stress enough how wrong it was to do what he did

It can happen in any family OP
DC are exposed to so much, hopefully with the NSPCC help you'll all get over it.

I wonder if there anything sinister at all, OP. It seems like it was just a spontaneous action. Less 'serious' (as in less able to misconstrue), but a remember biting my friend's (clothed) bum when I was about 5 or 6. She was faced away from me and crouched over. I have no idea why I did it, but it must have just looked appealing.

I hope that nothing has occurred to your DS that has caused your DS to do this, and that the NSPCC help you with how to approach it, and how to get to the bottom of it.
