My first born was made to engineer… I mean seriously he is always creating and configuring. His mind is on constant go mode.
At some point this week he was watching {another *eyeroll*} YouTube video about building with LEGO, and today I saw him pickup a book about LEGO machines (amazon link below) that he had gotten for Christmas. Within a few minutes he had come up with his own little machine and I am, once again, impressed.
