I don't have a nap schedule for my 5 mo, but I do have a scheduled "quiet time" for my 3yo. I think this is more for my benefit than anything, but everyday at 1pm, we put a child gate up in the door to his room and he plays in his room for a few hours. This actually started out because we are a one car family that is needed by my dh for his job. That means we are home all day long with the tv on WAY too much. Now, to avoid too much tv time we have our quiet time and I gain some much needed sanity every day. If I want to take a nap (not that I ever do take naps though) I can, and I know he's in a safe room, and if he needs anything from me, he just calls for me. Maybe you could try something like that?
