At approximately 6:15 pm, Maryn rolled from front to back ... about twenty times. She doesn't really get a lot of "on the floor" tummy time as it is not an entirely safe location with brother around. She could have been able to do this for weeks... She rolled from front to back on both the left and the right. Seriously, she is gonna be a mover and a shaker! We are so proud of you baby girl!
