My DS13 was doing similar things at just over 2 years of age. He could take a 40 piece puzzle of the USA and do it very quickly. So, I thought it would challenge him if I flipped all of the pieces face down and mixed them up. To my astonishment he picked up the pieces in the facedown position and moved them to the correct position and then flipped them over and put them in place. That, I could not believe. I also can't believe I haven't been able to find the video of it.
