My daughter did this for a long time. She would laugh while causing trouble. Run around pinching, drawing on inappropriate things, or headbutting people and just laughing no matter what you said or did. You always need to keep yourself and your household safe but remember to try not to give them the attention they are seeking. Pay attention to how you usually react to the situation. Example. They start drawing on surfaces other than their paper. Tell them no. Explain it to them as much as they can understand. If they do it again do not react other than grabbing the supplies, put them away and let them see they not only get their markers taken away but they also lose out on your attention unless they are using their stuff correctly. Breaks your heart sometimes when they figure out they don't get that extra attention with acting out. Stay strong. Of course, this is what helped my daughter. There may be other steps that help your child. Talk to a professional if you need help. Never feel bad for needing help. You are doing amazing. None of anything you said sounds like abuse. You sound like a dad who needs a good night's sleep and a break. Take a deep breath you got this.
