I told our kids. My son was home when I found out about the "last" OW---there is no way it could be kept from him.
I learned much later--after WS and I separated and when our son was in a deep depression (which predated d-day, but at that point was manifesting physically, as migraines)---that DS had overheard his father on the phone with someone NOT me (because, well---I was right there), talking in a way that should have been reserved for talking with me. This occurred WELL before d-day---a good 2-3 years.
So on some level, he knew. And this knowledge, held in (because he had NO idea what do do with it, poor child), made him PHYSICALLY ILL. He also blamed himself.
It was a relief for him when it all came out. And it was even more of a relief when I then recognized his physical symptoms (for which he'd been given serious meds, endured serious and expensive tests, and missed MASSIVE amounts of school) as part of a major depression.
My daughter was away at school. And yes, I told her, too. It was very difficult, but lies are what got us here, and I was damned if I was going to contribute to the atmosphere of dishonesty.
My husband was aware of and "supportive" (and present) when the kids were told.
He then was irate. And now he blames me for his lack of relationship with both kids. (Never mind that he's completely absent from their lives--in every way.)
His kids have ZERO respect for him---every single bit of it deserved.
The sad thing is that they both WANT to respect him. They love him. And he is totally unworthy--because he is utterly incapable of loving back. Unless he's getting that heady (heh-no pun intended) narcissistic supply, he has no desire for contact with anyone. They remind him of his failures, so they are .... history.
