No leaks!

So we have been potty training N, and for the most part it is done.  However, we still put a diaper on him at night, just to be sure.  Aparently this isn't enough for him though.  This is how we found him last night when we went in to check on him.  

Yes, that is a pair of underwear on over his diaper, or at least that's what we thought.  When I got him up in the morning, I realized he actually had put on two pairs of underwear over his diaper sometime in the night.  

This isn't the first time he's done this either.  One night last week we found him with two swim diapers pulled on over his diaper.  Apparently he wanted to make sure he was covered!  Crazy kid...
