what does it actually mean?

I see that at 2yrs toddlers can stack 6 blocks… As Kyle loves blocks and have been making stuff with it for a long time I wonder if this stacking 6 blocks means just simple blocks like the one attached? *6 of it i mean…this ones got more than 6!

or the second one

And is it smarter to stack bricks over blocks and vice versa?

my son uses lego size bricks now and make stuff with them so am just wondering if hes gonna be a constructer :wink:
