There's doubt in my mind that your child is profoundly gifted. Every gifted child is unique and develops differently. My child said his first word at 5 months and is speaking in up to 9 word sentences now. He is also reading. His gross motor skills have always been slow to develop. He didn't walk until one day prior to 15 months. He is day-time potty trained and even uses the bathroom standing up at 2 yrs. 3 mo. He has great fine motor skills and loves puzzles and drawing.
