Turning Over

So apparently today is a big developmental day for JJ. John got home and was playing with him during tummy time. JJ was getting a little frustrated, so John says "hey, you just have to turn over. See put your arm down here and kick your leg over and ta dah! You're over" And he demonstrated by rolling over himself (very funny btw). JJ looks at his daddy very intently for a few minutes then BOOM, he rolls over just like John did! Wow! If I hadn't seen it I wouldn't have believed it!
