I went to a fortnightly morning tea gathering for a few months, years ago, DH was studying at a university in England and this was for overseas students' wives. One woman sometimes turned up with her little daughters, very close in age, and inseparable. They played together happily, but there was something I couldn't quite figure out. One day I was playing counting games with them, tickling the palms of their hands, and one girl had the typical Downs hand. So I spoke to their mother, and she said that the Downs daughter was the eldest (there was also a baby), and she and her husband had decided to have another child as soon as possible, so the little Downs girl would have someone to play with and learn with. I was impressed by their thinking, and by their sheer courage. And it was working very well indeed. Two beautiful blonde toddlers, indistinguishable. I often wonder where they are now and how life has turned out for all of them.
