Our younger one was drawing with crayons long before he turned 1. My guess would be around 9 months or so. His brother was drawing and he wanted to try it as well.

As for all of them being above average I think it's not unusual or even surprising. IQ depends on nature as well as nurture. Most of the HG+ kids have gifted parents. If I remember it correctly 60% (or was it 40%) of the siblings are within 10 point difference on IQ tests.
