Yay on Seths block stacking, what a smart little bub! And all the other bright babies.

I think Logan started knocking blocks down when he was 9months (he couldn't stand seeing anything stacked or even stand anything being on a surface within reach, he would happily make sure that everything was in a heap on the floor), and at 10 months he was stacking blocks and using the shape sorter.

At the moment his newest tricks are trying to take things apart and opening things with lids, especially screw tops if someone hasn't done them up tight enough. He loves to unscrew the lid for the dogs dry food and "feed" them.
