Noah is officially unstoppable

Noah has been climbing the stairs for several months now. However, up until now, someone has always been behind him just in case. Knowing that he likes to climb the stairs, we keep the living room door closed when he is downstairs and we have to take our eyes off him for a second. Today, however, he managed to open the living room door and climb up the stairs to my office (where I was) while Yukari was outside getting ready to take Noah for a stroll in the stroller. It happened so quick that I didn't even notice Noah until he had reached the top of the staircase. The smile on his face seemed to indicate that he was very proud of his accomplishment. I was excited to see his initiative, but I think Yukari almost had a heart attack when I told her what Noah did.
