6 months old and growing

So Camilla is now 6 months old and I can not believe how big she is! 14 lbs 2 oz and 25.5 inches long. I am getting low back pain from holding her! She can really roll around and pivot on her stomach. I like to put things just out of her reach and watch her maneuver to get the object. (sound a little cruel but the pediatrician said it is good for her problem solving skills)
Also, the other day I saw her using her thumb and index finger trying to pick up a piece of lent off the floor. This I have come to understand to be the "pincer grasp" which babies tend to master between 7-11 months. ( I new she was smart!)
Something we need to work on though is "sleep training". Right now the only way to get her to sleep is to nurse her. I need to start putting her down in her crib drowsy. (according to the "experts" and the pediatrician) But it is so hard listening to her cry!
As far as hair, she is still pretty much bald. She had more hair at birth, or maybe her head has just gotten bigger. Although she does have one strand of hair I swear is 4 inches long!
At about 5 months I started giving her "real" food. So far she has had bananas, peas, broccoli, yogurt(soy) apples and rice cereal. The look on her face when I gave her the broccoli was priceless!
We are having lots of fun with for sure!
