Give her whatever you're eating. At 10 months the only thing she really needs to stay away from is honey and peanut butter. When my dd was little she loved mac & cheese, chicken, meatballs, hamburgers, bread, crackers, cheese, any and all fruit, some vegetables, mashed potatoes, yogurt, and just about anything else! I would just make sure things were cut up small enough that she couldn't choke on them. Of course, my dd didn't have any teeth till she was a year old. The biggest thing is to sort of ignore the mess. She's going to make a mess and get terribly messy. It's just the way it is! Put an old sheet under her high chair to help w/ clean up and strip her down to her diaper. Oh, and get the camera ready. Mashed potatoes in the hair makes for great pictures!
