Baby Kumquats

We're at week 10. They are finally fetuses or is it feti? I feel great and spent the Columbus weekend in Boston walking miles and miles all day.

Here's what's going on with their growth -- Though they are barely the size of a kumquat — a little over an inch or so long, crown to bottom — and weighs less than a quarter of an ounce, the most critical portion of development is complete.
The fetal period is a time when the tissues and organs in his body rapidly grow and mature.

They are swallowing fluid and kicking up a storm. Vital organs — including his kidneys, intestines, brain, and liver (now making red blood cells in place of the disappearing yolk sac) — are in place and starting to function. Details are starting to form like tiny nails forming on fingers and toes and peach-fuzz hair beginning to grow on tender skin.
