Toddle quiet time ideas?

My toddler has started to resist his naps so I am insituting quiet time (which often ends in him falling asleep because he needs to sleep but is exerting his independence like none other). We have special quiet time toys that he looks forward to using and up until today I was letting him do it on the couch with a show on. But we’re getting a nanny and don’t want her to have nowhere to hang out during quiet time so we want to move his quiet time to his room. The problem is he sees it as an opportunity to be independent and just continuously comes out of his room and we have to lead him back in every 5 seconds. Today I put my laptop in there with a show on and he fell asleep. I don’t necessarily want to do that every day though.

So I’m curious what you do to help your child stay in their room for quiet time? We want to get a CD player for him to listen to books/nursery rhymes/nursery songs. Any other ideas?
