I know what it's like to lose all rationality over sleep issues. It's tough. In terms of etiquette though, I'm not sure you have any grounds to ask them to stop playing. Perhaps it is a phase that the 7 year old is right into basketball atm? Has it been going on long that they play hoops every afternoon?

I was thinking the same as Heaven - either trying to move DS further away in the house to another room for that sleep (a port-a-cot or the pram?) or going out with the pram for a walk. Could you wear him in a sling for that sleep so he re-settles quickly if woken?

Try to remember that one day, it will be your DS shooting hoops or doing some other noisy activity in the backyard and bothering the neighbours.
