Dd has a small head. She is a preemie and her head has always measured in 10-25th percentile. I was worried when she was little because she looked more like a doll than a baby but the doctor assured me that abnormally big heads were more of a concern than a small head. I have no idea how gifted dd is but at this point I will be surprised if she not gifted. Glad that a small skull has not yet hindered the ability of her brain to flourish.
