OP's son might be very young, in which case I wouldn't advise simply telling him to sleep on the couch. That's a little cold to tell a little kid IMO.

There's nothing wrong with kids sleeping on couches. Heck, I make my kids sleep on piles of rags in the basement, and they seem mostly alright. I even give them blankets sometimes.

That's why a parent can put down cushions/pillows/blankets to protect the child should they roll off the couch. At least they'll fall into a soft area. But, then the child can still sleep and the mother as well.

*HollyQuinn locks eyes with her partner, smiling slightly with concern in her eyes* "Look, you know how much I love you, and I've hinted at it before, but… ugh, how do I put this best? You see, when it comes to having kids… there's this FML—" "The cockroach one?!" "Yeah! Well, one of the cockroach ones." "Say no more. I'm not looking to have kids either."

That's the negative aspect of it

So that's why I came home to ashes instead of a house. Sorry about bringing you to court then, buddy, I didn't realize there was a cockroach
