Just be honest ... Even if your child cannot speak yet they understand a lot. Talk to them, let them know that your eyes font work like most people's eyes. Let them know what you can't see and maybe turn it into a game. My child was 3 when I could not longer "fake it" anymore. I would walk with him and just talk to him about what to watch for with cars and in intersections. By the time he was 4 he was such a huge help and would feel so proud that he could help me know when we could cross the street or if we should wait for a car because the "backup" lights were on.

Now he is a teen and he is so helpful and one of the few people I can laugh with at myself for "blind mistakes."

One tip that helped me teach him to read was too get him a tablet and to download a kids reading library. We still got the experience of reading books before he want to bed and he was able to follow along because each word that is read is highlighted.

just tell the kid you can’t see it, I have to explain it to my nieces and nephews and they get used to it pretty quick and as they get older they like helping me out, one will point at something and the others will bring it to me or explain what it is so I can answer the younger ones questions they get really proud of themselves about it too.

He already knows. Your job is to provide a framework of interaction. Things like 'show me where' and letting him lead you or allowing him to point your hand in the right direction for getting things. Teaching him how to make noise so you know where he is, or using noisy socks or bell bracelets so you can locate him. Teaching him to keep toys out of pathways is another important thing. As he grows, these basic things grow into subconscious signaling when he's around you or not moving things around or telling you if he does.

These are intrinsic blind culture things you may not have thought of that make your life easier that he will integrate as 'how things are' without being told 'because I can't see you.' The disconnect will happen when he discovers this isn't the universal norm. There's when convos happen. You've got a couple years at worst and possibly til kindergarten if you're lucky. By then, he'll have more words to address the complexities and more experience with you to see how things work differently rather than not at all. These are important tools collected over time that coalesce into growing understandings. My own childhood was a repetition of the 'pick things UP!' game that just seemed like a Thing to Be Done until my mother got seriously injured tripping over a rocking chair an adult left somewhere it wasn't supposed to be. Then it hit home that this was Important and not really a game.

Note: My mother was totally blind. I'm legally blind. My now-grown spawn is fully sighted but maintains his interaction skills. Human development and adaptive education are parts of my skillset, too.

Just tell them, repeatedly and often, because they won’t remember, but they will slowly learn. “I can’t see very well, can you show me closer?” “What colour is it? I can’t see the colours well” “Remember, I have to look up close because my eyes don’t work as well” And so forth. At that young, they won’t really get it, but they will eventually. And through repetition, they’ll figure out, this is the way that mum/dad does things, it’s different than others and adapt. Honestly it was kind of exciting as my niblings got older, probably by four years old, and started to understand that I couldn’t see as well. The youngest, at six, still needs reminders sometimes, but mostly gets it. Younger than that, they clearly didn’t really understand, but could still usually be persuaded to bring things closer to examine and such. I assume this process will probably take less time we’re it my own child because I’d interact with them every day, rather than every couple months.

You’re definitely right about mobile being accessible I like the concept of an AI guiding the player to the levels I guess the most advice I can give is obviously focus a lot on the audio make sure it’s clear and use it to also help guide the players such as putting sounds near the end of the level one of the only other games that I can think of to use as an example that sounds similar to the game that you’re making is something like the night jar maybe try looking at that as an example it’s unfortunately no longer on the App Store but you can still look at gameplay on YouTube and definitely make another post for when you release the game it definitely sounds interesting can’t wait to play it

For me, I did not have to let my son know, he slowly became aware and was bright enough to pick it up
