That must be Rebecca, with the symmetrical hair. The lines above the wall look like barbed wire, but are actually supports for the neighbour's grapevine that grows over the gate in summer, sometimes inches in one day. We don't live in that house any more, and the grapevine is the only thing we're going to miss (we've planted our own, but they're not high enough to give any shade yet). That the grapevine is not in evidence means that the picture was taken in spring, when Rebecca was about seven months old and just able to push herself in that position.
