Yash has been on the path to turning over onto his stomach from his back for a while and he is about to do it.  I am shocked that no enterprising inventor has not created some kind of gyroscopic doodad that can get this fellow turning over quickly.  Mom is the tummy time Nazi and makes sure that 20 minutes of TT gets done everyday.  I am pretty sure that Yash knows what tummy time means because as soon as he hears someone say it he spontaneously vomits and urinates in a natural defense.  Kind of like a skunk.
