April FOOOLS!!

Today was April Fool's and the kids, like the rest of this week, have been silly and rowdy. They had to go down for another nap because they just will not listen or follow directions. The teacher thinks it's the time change but I personally have NO IDEA what is going on. Could it be possible, that even weeks later they are now barely showing signs of exhaustion? The time change is barely hitting them? Could it be that even one hour of difference can affect them this drastically?
