When trawling through some photos on my computer today I found a photo of Ishie taken 6.5 years ago. I was struck how she looks like Harriet at the same age that Harriet is now (5 months). Both also have the same ... or similar ... character, i.e. like to be included in the chat, like to blether!
ANSWER: Harriet is the top photo, taken today; Ishie's the bottom taken in the garden about May 2007.
