Wardrobe Change

I just walked into Collin's bedroom to give him another kiss good night. I noticed that he pulled off his PJ bottoms and threw them on the floor. This used to occur infrequently, but he is doing it more regularly.  If he wakes up enough to pull his PJ bottoms off, maybe he is not as heavy of a sleeper as we thought. Does this mean that he is too lazy or tired to get out of bed and go use the potty?  He did have a dry night last night and was happy to show me this morning.
