Just for fun, could you share your experiences of your differently gifted kids, please? I have one very mathy son (DS6), and my other son (DS15m) seems to be more verbal. Both completed their milestones (from the column on the right in the link below) at exactly the same age (within a week), except for my eldest who could count to ten by one year old. My youngest hasn't shown much interest in numbers, except to point at them. He does, however, have a big interest in scribbling by 11 months. My youngest also just appears to be older and understand an unbelievable amount and has a wide variety of interests; my eldest was always very focused on just a few things.
