I don't know if my issues could be solved with a course.
The problem is that all the issues stack.
So my kitchen is a disaster and nobody has any plates/pans/etc available. Nobody has emptied the dishwasher, so I can't even wash the stuff that we have. There are maintenance issues in the kitchen so there is no hot water supply there and no hand wash liquid, so can't hand wash dishes.
Don't have the mental energy or "spoons" to wash dishes before preparing dinner anyway.
We probably forgot to go shopping and nothing healthy is in the fridge. Or I forgot to take that thing out of the freezer to defrost.
Medication is wearing off just at dinner time and I'm rebounding which makes everything even harder.
The kids are whining and that's causing sensory overload. The kids may have sensory issues themselves around food or food sensitivities.
I forgot it was dinner time until the kids are going crazy so I need to get something on the table for them in preferably under 5 minutes. It needs to be something palatable for them, otherwise they will refuse it, because they are now overtired and hungry.
It doesn't matter what I've read in a book or learned on a course, because that was a totally different situation/environment, and learning skills with ADHD does not transfer to a new environment and routine, they need to be developed or learned IN the environment where they will be used.
Many, many, many ADHD families have very chaotic surroundings with multiple issues. And they need something which can be right there at the point of performance - an online course is great but totally useless.
