7 month birthday

Sophia is 7 months old today, and she seems like a totally different child, overnight!  She has been constantly rolling back and forth all day, which was not something she did very often before.  Also, when she is on her stomach, she turns her body around in a circle to face a different direction. We didn't think she was going to crawl, but maybe she will!  She is finally allowing for her hands to touch the ground, which she didn't really like to do before.  We've also had her in her walker a lot, like we usually do, but she all of a sudden can really move!  She has tipped over the garbage can in the kitchen and has tried getting into the dog food.  I guess it's time to childproof!
