My own kids never napped beyond about 18m-2 but did get a full nights sleep and I was ok with that. I liked having alone time with them in the afternoon. I would put child in a pnp somewhere not in the same room with the others but where you can check on him if desired - even a hallway. No toys, no nothing just him in the bed. Quiet time is about staying in one place (pnp) and getting a break from having to interact with everyone else not always about sleeping.
