Definitely not our case. A few weeks ago I found DYS6 on the top of a climbing wall crying because he couldn't get down (his friend helped him up) while DS4 was happily climbing up and down.

I have early walkers but to me DS6 seems quite uncoordinated doing some things even though he can ski, ice skate, and roller blade pretty well. DS4 is a different story. He just started riding his bike without a training wheels.
