HILLARIOUS thing just happened

So I changed Brendan's diaper and put him in his crib and washed up and sewed a bit. When I went in about 5 min later I was shocked to find a naked bum! I couldn't see the diaper so I thought "Am I crazy? Did I forget to put a diaper on him?!" Nope it was under him, He'd undone one side of his BumGenius OS and crawled out of it. He was VERY upset when I plopped him back on his changing table to put it back on. I laughed for at least 5 min straight! Just had to share!
