I'm sorry for you all newgran. Just a thought about contact centres, please check rules on phones, tablets and the like. Some forbid them, or anything that could connect to the internet or take photos. In terms of play things, I agree, cars are good in fact anything with wheels, a couple of books with characters your grandson likes for tired or quiet times, those very useful colouring books with special felt tips that only show colour on the image, sorry can't recall the proper name. A drink and small snack can be good, and yes bubbles, your grandson can chase them you can sit down. Just go and love him, it's hard to be so constrained but you can keep your relationship alive. Wishing you well.
