You need to implement strategies that get you out of the middle of it and take the place of your reminders. Create process checklists (morning, bedtime, individual chores, etc). Working memory, part of executive functioning, is often an issue for those with ADHD, so they get lost in the middle of the process or feel they’re done before they actually completed all the steps of the tasks.
You can hand write and post lists/processes or use apps. Some people even use a device like Amazon Echo/Alexa to give reminders, so parents don’t have to nag. https://www.additudemag.com/product/echo-dot/
