It's really great to use a responsibility chart when you're working with kids. An example is a magnetic chart that's easy to move around with mini choices like getting dress, making the bed, and other things you'd like to include. It is also advised to have the days of the week written on it so you could tract and monitor then at the end of the week, it'd be good for the kids to see what they have accomplished throughout the day. It would also be nice to give them a price like simple stickers to get them more motivated;
One with a whiteboard part is also great where you could write notes and reminders. Or a simple but creative home made chart with pictures is also a great idea since some children works very well with visually prepared scheduler. An example on something very simple and easily homemade chart is for exploring hand washing, where it shows pictures of each steps, like, turning on the water, washing your hands, or get your hands wet, then using soap and scrubbing and making bubbles. And then drying your hands off.
You can put words at the bottom if your child could read. That will surely helps them. You can make them in color, black and white, whatever works for you and your child.
Also when you're doing activities of daily living, such as dressing, brushing, eating, and washing hands. Try to use more gentle physical prompts instead of using a lot of language.
Don't ask the child what's next, what to do next, or what comes after ~ a lot of children that have special needs, or even typical children that processing time when you're asking them lots of questions, becomes way too much for them.
If you use something simple like a DIY chart, the kids could easily figure things out. You can also use some clip arts from your computer or you could even let the kids draw. It makes it more fun and appropriate for them.
