First time rolling over (4 month old)

July 14 2010
I was wondering when this was going to happen, she wasn't even trying to role and all the babies around her age were already going from back to tummy and tummy to back. I'm not going to push her although we have been encouraging her when she's been on tummy time. Well low and behold, whilst laying on her mat on the living room floor she was trying to get to a toy that was slightly out of reach, she lifted her legs and looked above her and over she went, back to tummy. I thought that was a fluke because she did that once before on a soft surface, well she did it two more times that day and when I went to check on her in her crib whilst having her afternoon nap. I found her half on her side half on her back (see picture) she's been rolling everyday since :-)
