Trying to model Christ-like patience when my kids test every limit

Man, this is harder than I thought. My 7yo deliberately disobeyed me today and I felt my blood pressure spike. Had to walk away for a minute and literally pray before responding. How do you guys handle those moments where your kids push you to the edge? I want them to see Jesus in how I discipline them, not just see an angry dad. My wife reminded me that they're watching how I respond under pressure. That hit different. Anyone else struggle with this?
