there's the tower

Today we went up Sky Tower and of course Liam loved it, even though when we were up there he'd look at other towers out the window and say 'there's a tower'. He always says this about the Sky Tower but i'm not sure he realised we were up there. He had a good time anyway, and the height didn't seem to bother him at all, he'd walk straight over the glass floors which i was abit hesitant to cross.
We bought a two dollar height chart for him which a picture of the tower on it for him, he's obsessed with it! He's saying 'there's the tower' constantly.
