Honestly, I'd suggest counseling for the boy, then for the mom, then for them both together. And if she's going to discipline, she has to be consistent with it, and the time has to fit the crime. Does he wet his pants on purpose or is it an accident in the night, or while getting too involved with playing? My 7½ yr. old son still wets his pants at night, on occasion, and he's been known to have an accident while playing because he tries to hold it. If he's doing it out of spite, I don't think spanking will help, honestly. It sounds like that's his way of getting attention from her and she needs to address that issue, which is the root of the problem. The knives and matches scares me and makes me wonder where this child is, emotionally. Setting aside a date day each week, for her and him alone is a terrific idea, but again, consistency is necessary. And being a single mom, I know it may be difficult for her to commit to that. I have 2 boys, the same ages as your friend. And I try to make sure and steal away some special time with my oldest on a regular basis, because I know I get wrapped up in my youngest, due to his developmental delays. So if the older one has a dr's appointment, or just for the fun of it, I will take him to Dairy Queen and we get ice cream cones, or we go to the park, just us, or whatever I can think of. And I make sure to stress that I want to spend time without his brother, and just with him, because I love him and miss our time alone together. I make the focus about him. He was the focus of our lives for 5½ years...so it's normal for a child of that age to feel jilted and left out of the loop when a new baby comes...especially in our case where our youngest was 8 weeks premature and has had problems ever since. So sometimes I just have to step back and put the focus back on my oldest. But I still stand by the counseling advice for your friend. It sounds like she doesn't know which end is up, but wants to fix the situation with her son. And it really sounds like he's going through more than she may ever realize. I hope they can get this straightened out.
