kids and poop go hand in hand

Literally.......if you have a weak stomach stop reading now. I kept smelling something and could not figure out what it was. All kids had been changed only a minute before. No poopy diapers. I feed all three kids and still can not find the source.....until Brock puts his thumb in his mouth and I notice something in his hand. At first I thought he had one of Oaklen small toys, but it was not. It was a small brown dime size smooshed hard poopy in his hand and almost touching his lip. Where did he get it? I have no idea but I hope there is no more where it came from!
