Arthur Chang was so kind to hand us down a tummy roller designed specifically to ease babies into spending more time on their tummy.  Ethan still dislikes being on his tummy.  When we place him on the roller, he actually tolerates being on his tummy and gave us the sweetest smile.    Now that he can roll back onto his back, he would do so the second we remove the roller.  And gives us naughty smile, “Ah ha… you cannot force me on my tummy anymore”.   We have been encouraging him to roll over on his tummy, but he remains on his back position.
