Diaper issues

So our little Landon has hit that stage where he is always trying to pull off his diaper. I have started to put him in rompers again that button at that bottom, but it is not always so successful. Case and point, the pic below. He has learned to unbutton the snaps. So this is what we found at nap time, thankfully his diaper was still intact. And here's a close up of the sleeping angel. Isn't he precious?!?!
