Thanks everyone! She always has her eyes open underwater, and I sometimes wonder what she sees. I suppose it doesn't make sense that she should be able to focus any better than the rest of us, but she definitely turns her head towards objects of interest. I have open eyes myself when I dive, but without goggles, everything is just blurry blobs of colour (which, incidentally, doesn't improve my handling of the camera either. And with goggles, it is hard to get my face near enough to the viewfinder, so there is a big amount of luck involved in framing the shot. More so, because the water magnifies objects, so 18mm under water is a much narrower angle than 18mm above surface!)
Kerrowdown: I tried to do the Nirvana cover (without the bill anyway) with her, when she was a bit younger, but with the WG-3 I was never really satisfied with the result. Now she IS a bit big - more toddler than baby, but yes, I see the ressemblance too. She clings to a coffee cup rather than a dollar bill, which reflects her mums values quite well too...
Slowpez, I have been thinking water nymph too!
Our swimming teacher calls her "the mermaid" because she has no fear of water at all. Which is a good skill at the pool, where the only real danger is to panic - but I am a bit anxious about taking her swimming in the ocean this summer: She needs to understand that not having a pool edge to swim to sets new rules of caution!
