  I've been avoiding fiction because I don't want to find a story that makes even the vaguest reference to the death of a child, but of course, non-fiction is just as bad. I was reading urlLink Lost World by Tom Koppel and he talked about a paleolithic skeleton that belonged to a small child - and even that choked me up! It's really terrifying, this parental love. It helps to remind myself that in the U.S., urlLink 993 babies out of 1000 make it to the age of one, and a higher percentage of those to the age of four.
Aside from the child bones, Tom's book is a surprisingly entertaining read about scientific investigation into the Bering Strait theory - the idea that Asian people walked across a land bridge into Alaska and down a corridor between glaciers to populate the rest of the Americas. There's actually very little evidence for that. Tom hangs around with archeologists who explore caves on the northwest coast for evidence that people actually came by boat and settled the coast - long, long before the urlLink Vikings.
His descriptions of crawling uphill through narrow, lightless tunnels make me shudder. Spelunkers! Today I took some baby stuff over to C's apartment. She's getting more stuff than she can actually use, but fortunately a couple of relatives are each pregnant with twins. Her pregnancy has taken away her sleep, and she looked exhausted, but lovely nonetheless. She looks very Asian, a descendant of those paleolithic migrants.
