Can I make my child dependant on a fidget cube?

[AmazonPrim]

I think I already know the answer to this, but my husband always makes me second guess myself.

Back story: I am diagnosed with adhd and am on medication (fairly recent diagnosis). I suspect my son is ADHD and likely ASD but husband is very dismissive of it and will not let me mention it or entertain a conversation about it.

My son was getting very distracted while we were trying to watch a movie so I gave him the fidget cube that I put in his stocking. It was making a faint clicking noise, but he was paying attention to the movie because of it. Husband was getting annoyed at the clicking and told him to stop it and put it away. My son said “I knew it. I knew dad didn’t want me to have it.” I told him that I said he could have it if it’s helping him. Husband got annoyed and started saying that it’s stupid and he will become dependant on it. I told him that’s not true and he said yes it is. Science says so. I could see my son fighting back tears 😔

There was a part in the movie where they give some troubled children some kind of tranquilliser medication to calm them down and make them compliant. My son was asking about it and my husband was saying all this dismissive stuff about medication like that in general and about brain altering drugs. Just making them out to be very bad knowing that I’m on them and my son most likely should be on adhd medication (I am). So he’s purposely making it seem like they’re all terrible and will mess your brain up

Anyways, is it actually possible to create issues like dependance on something like a fidget cube? He thinks it makes your attention span even worse and makes you used to constant distractions

The way I understand it, adhd makes the brain work 'fast' and gets very distracted due to its constant need for input /stimulation.
Hence the fidgeting, lack of concentration or hypefocus on irrelevant things.

If you can find another way to give the brain this stimulation, it will not need to display all the adhd symptoms and allow the person to concentrate, and function more easily.
Some ways to offer this stimulation are medicine and fidget toys.

So they are giving the brain what it needs in order to allow the person to function better in our society, which says they must act in a certain way.

So the fidget cube can't become addictive or damage him in any way, it is offering his brain what it needs to allow him to do other things at the same time.

Thank you for this reply. Makes perfect sense. I struggle to try and explain things to him that make sense. I will try this
