An Alexa can also help move them along. You can schedule countdown timers, reminders,etc.
My ADHD husband has made tremendous improvements with technology. But it also took things like me showing him over and over that he simply isn’t capable of getting ready in 30 minutes. And that if he would like to get to church on time, he needs to assume 45 minutes of getting ready AND another 15 minutes of getting kids ready. He would not build in the kid time and I was pretty much like “F this. I’m not doing it all so you can add time or we can not go.”
We were recently super late to something for his family, because he has yet to grasp what our ADHD teen daughter needs to be able to leave at a certain time. And I’m just like “whatever.” He was pretty panicked. But (as I had predicted in my own head), his whole ADHD family was late too so it didn’t matter.
But honestly, he is on time the vast majority of the time. He uses alarms on his phone. And we talk through the schedule each weekend and he puts everything in.
My family on the other hand generally arrives 30 minutes early, which makes my hsuband totally insane.
