I'm interested in your experiences on this: my 2 1/2 year old has been doing his brother's 60 piece age 4+ Monsters Inc jigsaw on his own with great ease for the past 3 months or so and this week did an age 6+ 80 piece pirate jigsaw on his own with me just putting pieces in the right area for him to fit in. His dad is a mathematician so I suppose it's an heriditary thing, he has a lot of patience for it. Does this mean he'll probably be good at maths?
