Have you tried the Siblings Without Rivalry approach? Pay attention to the victim, tell her that "Poking is not okay.", ask her if she is feeling better, take her to another room. Don't engage with your son. Don't give him your full attention. This tip has really helped me a lot with the "skooching" problem (love the name, by the way). I know an eight-year-old who still skooches babies, so I was particularly afraid of it becoming a long-term problem.
