Well, our underwater photographs arrived and they really are very good.
All apart from this one.
This is the one where, in order to try to get a shot of the two of them together, I had to let go of Gertie as she held on to Gilby underwater. The one where, by the time we arrived at nursery in the afternoon, and we had praised Gertie for being so good in the water and holding on to her little brother, it had turned into a great tale of how she dramatically 'rescued' him.
Generally, and I am clearly biased, I have very photogenic children. On this occasion, however, it appears not. Rather than a spectacular underwater rescue, it looks more like Gilby is desperately trying to escape the clutches of his big sister before he runs out of air. And she, bless her, is clinging on to him with all her might, just as she promised her mother she would.
The photographer warned me, as he looked though his viewfinder, that this one might have 'comedy value'.
