Firstly it sounds like whatever you have been doing so far is working really well, so be kind to yourself. This will get easier with time as your child gets older.
I'm in a similar situation myself but my children are now teens.
Autism and ADHD weren't as focused on back then though so I just knew I had traits that had held me back in life and didn't want them to be similarly affected. They are all now what would considerd to be ND traits.
I worried they would learn certain behaviours from me so have covered up how uncomfortable/ overwhelmed things make me and compromised throughout thier childhood, often at the expense of my own mental health.
I ate food that I didn't like, attended environments that I found uncomfortable. All in the hope they wouldn't face the same limitations as myself. This would now be defined as masking.
I would be good at coming up with things that were within my limitations. Take for example, another mum would take mine to a play barn, they are like hell on earth to me, so to repay the favour i'd take them out to the cinema. A far calmer situation for me to deal with.
I'm not overly keen on friends being at our house as it it makes me very uncomfortable. But I don't want to be that house where no friends come round. To compromise I just need to have a set going home time. If I know what time they are leaving it makes it far more managble and me more hospitable.
My eldest child shows some ND traits but are far more confident than I ever was.
Both have no issues around food which has backfired a bit as they now cost me a bloody fortune.
As they have got older, I've been able to let the mask slip. I can get away with not having to eat certain foods which makes meal times more enjoyable for me. I'm also finding it easier to have more alone time to recharge as they need me less.
It does get easier
