I had 2 children like this in the past. You can't even pick your nose if you wanted to, heaven forbid swearing under your breath. LOL

What I did was make them my assistants, I would ask them to help the smaller ones in the bathroom with the light or washing of hands, help with getting everyone else's coats and shoes on. I would hand them feather dusters and ask them to dust. I would give them some wipes and ask them go wipe down surfaces in the playroom etc...

These kids are are shadows and love being around us as they are mommy's girls and home bodies. They are amazing visual learners.

Don't get mad just try and understand the world from there perspective. In my experience they also love to draw, do puzzles and look at books. Maybe have an activity corner for them in the kitchen. These kids are also introverted and a lot of loud imaginative play exhausts them.
