Rolling over some more

Since 3 months old, Sophia has been able to roll from her tummy to her back, but she hasn't been able to figure out how to roll from her back to her tummy. Finally, last night, when reaching for a toy, she finally figured it out. Today she rolled from one end of her play room to the other trying to reach a toy I kept moving away from her. Babyproofing this house may need to start soon!!! We're so proud of her though.
