That all changed last week. From the first few tentative gropes on all fours, he's now rocketing across the floor, generally leaving a trail of destruction in his wake. So far we have relocated a few dangerous items to keep them out of his reach and we are now learning the benefits of an obsessive neat-freak's style of living. He goes whipping around until he can find something to pull himself up onto two feet with, like the sofa, the TV shelf or the table. Whatever happens to be on one of these surfaces, and within his reach, he instantly deems to be a hindrance to his exploration and therefore consigns it to the floor. Mummy and daddy follow him, picking things up and reminding him that these things are there for a reason.
Either that or we're giggling along with him and videoing his escapades.
