This kid is busy.  Busy getting bad guys, busy making sound effects and doing his happy dance, busy building with Legos and setting up action figures.  So, when this little dude's body says rest, I let him.  Even if it is before lunch, out in the living room, sprawled between his toys.  He wakes refreshed and ready to face the world and it reminds me that even though he's 4, he's still my little baby.
