Does anyone else love watching them solve problems?

Maxi absolutely loves magnetic shapes and will build with them all day! He’s learnt to build a pyramid independently, he does it flat/2d then raise it up to make a pyramid! I couldn’t do this I couldn’t picture a pyramid as a flat shape! Once he did the flat shape he was muttering carefully, don’t want to break it! Maxi is hyper fixated on shapes at the moment and know 2D and 3D, he sees shapes everywhere we go!
