>>>It may just be that he's lonely and misses being close to his kids

That is still weird. I could see the kid climbing into her dad's bed....but the other way around? It's just creepy.

I don't even see how this would cause trouble with the ex. It's an issue that needs to fix itself immediately. If everything is innocent, he can put her mind at ease by agreeing to not do that anymore on a regular basis. If he's got incestual issues...well...at least he knows she's on to him. Either way, it fixes things.

I would also definitely research the issue on the net, and find out good ways to talk with your kids about sexual abuse. Every parent needs to have that talk anyway...now is a good time! It would fall under the same talk as "don't talk to strangers, don't accept candy or follow strangers, don't let them touch you here...etc" They need to know what is acceptable, as well as how to react and who to tell if it does happen.
