A kumquat!

Babycenter's website has awesome updates they send out each week, comparing the size of the baby to something familiar (usually a fruit) and describing the week's developments. We're currently at 10 weeks and 5 days, and the 10 week email revealed:

"Although he's 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, your baby now has completed the most critical portion of his development. This is the beginning of the so-called fetal period, a time when the tissues and organs in his body rapidly grow and mature. If you could take a peek inside your womb, you'd spot minute details, like tiny nails forming on fingers and toes (no more webbing) and peach-fuzz hair beginning to grow on tender skin. "

Nails! Just last week the ultrasound showed only the very beginnings of arms and legs, and now we've progressed to nails. Wow!
