I don't how it works in your house, but in mine, "napping" is code for "mommy needs a break". Since we transitioned from cribs to beds, napping only occurs every couple of days. Still, everyday at about 2 o'clock i heard my trio up the stairs & in to their bedroom. They get into bed & pretend they are going to sleep & i pretend right along with them. Monday through Friday i quickly get ready to leave for work & weekends i rush around trying to clean the never ending mess that has become my house. They don't sleep, but for about 2 hours i listen to my girls play, talk, & fight. Only very occasionally do i have to go in and break up a fight. I love that they can usually work things out on their own. as they get older the words have come. They call out for each other, they sing, they count. They are learning to express themselves, unguided & unlimited. And sometimes, at the end of all that, they pass out. One sprawled out in the middle of the room, another one with her foot sticking out from under a bed, the third might actually be in bed.
If all of this sounds exhausting, it is. But it's also wonderful & i wouldn't trade it for the world. And after their "nap", i am refreshed & ready to explore the world with my girls.
