Life formed. That's a very big thing indeed. It's something of the most monumental unlikelihood that we can't comprehend quite how likely it is. It's less likely than me sitting through an entire football game without getting bored. However, once it developed, it didn't do very much more. Life remained comparatively simple. It did get more complex, certainly, but it did so very slowly indeed.
All of a sudden she's mastered a lot of skills. Crawling? Yes. 'Daddy, what are you typing about? I've always being able to crawl this well,' says Olivia. But she hasn't. Until this week, she's done about three or four steps on her hands and knees and stopped. Yesterday, she raced across the room towards the television at a rate of knots. Considerably more than three or four steps. Not only that, she was giggling like mad because I was chasing after her and she thought she might have a half chance of pulling out all the DVD cases and lobbing them on the floor before I got there. It was a naughty, 'I shouldn't be doing this, but I am' chuckle!
She's also mastered standing up (as long as there's an object to hold onto - she's not freestanding) and - as of yesterday - sitting down again.
If you hold her hands, she's now voluntarily moving one foot in front of the other to walk towards someone else. Until this week, you had to tip the whole baby one way and then the next, as though walking a large, unwieldy box along.
When I put her to bed, I laid her in her cot and did the baby sign for sleep; two hands held together, and placed under one side of the chin. She mirrored the sign, and she's also doing 'milk'.
So, that's Olivia's Cambrian Explosion. I've no idea how poor that analogy will turn out to be. Maybe she'll do similar things every so often (though perhaps this would be a 'Punctuated Equilibrium' equivalent), but regardless, her Jedi powers have become considerably more powerful than you could ever know in the last couple of days.
