I've been thinking about him all morning, feeling so ill, but so bored.
I've just joined Snapchat where you can put filters on your photographs, that might be fifteen minutes of 'techy' fun.
Not sure how many drips he has in, can he move his hands easily Mebster? Could you get him an old fashioned gameboy or Nintendo DS? Just for something different that he wouldn't normally use with his friends. My son learnt to read as he wanted to play his Gameboy.
When my husband was in hospital he liked to play cards and taught me every game he knew, I always lost ;)
I love the robot idea.
