Week 24 came and went. And she kicked and swished and prob'ly reached about a foot long, though fetuses/babies in the womb tend to, well, be in the fetal position. So she's not exactly stretching out, when she kicks and karate chops, she's just sussing out her space.
Baby Center describes the formation of tastebuds (! for the amniotic fluid/urine, yumm!) and she's getting ready to pork up: she couldda gained 4 whole ounces since the 23rd week.
As well: "Her brain is also growing quickly now ... Her lungs are developing "branches" of the respiratory "tree" as well as cells that produce surfactant, a substance that will help her air sacs inflate once she hits the outside world. Her skin is still thin and translucent, but that will start to change soon."
My analysis: glad she's still inside. As much as I'd like a kit with wings or a tail or multiple sex organs, I don't really want a see-through kid (AH, the inside out man from Fishboy!!)
Oh, and in week 24, I had a soccer ball in my belly (maybe a size 4?), or so says's the site: "In the past few weeks, the top of your uterus has risen above your belly button and is now about the size of a soccer ball."
