Saves time

A few weeks ago we noticed that Nathan would go to bed in pajamas but before he fell asleep he would change into his clothes for the next day. He wouldn't say anything, we just noticed when we would go in to check on him before we went to bed. Now he must have converted Zachary to this practice. I guess they feel that they can save valuable playtime if they don't have to change in the morning. I don't understand how they can possibly be comfortable sleeping in jeans but as long as they are sleeping and not waking me up in the middle of the night, I don't care what they sleep in!
