Your baby weighs about 10 1/2 ounces now. He's also around 6 1/2 inches long from head to bottom and about 10 inches from head to heel — the length of a banana. (For the first 20 weeks, when a baby's legs are curled up against his torso and hard to measure, measurements are taken from the top of his head to his bottom — the "crown to rump" measurement. After 20 weeks, he's measured from head to toe.)He's swallowing more these days, which is good practice for his digestive system. He's also producing meconium, a black, sticky by-product of digestion. This gooey substance will accumulate in his bowels, and you'll see it in his first soiled diaper (some babies pass meconium in the womb or during delivery).
Everything looked good at your ultrasound on Monday, and we confirmed our suspicions: yer a girl! Congratulations for graduating from Number Two to L'il Sis.
I'm not entirely enthused by the "princess" designation, but we operate under society's gender constructions so there it is. You will certainly receive some girlie gifts--in addition to getting Sam's hand-me-downs--and despite our best efforts you'll feel pressure to conform to roles that Rush Limbaugh and even enlightened liberal patriarchs still enforce, yet we hope you will at least be aware of the game.
Big Brother Sam appears to be grasping the fact that you're on your way and are a girl (though he still has trouble with correctly pronouncing 'sister' and 'brother'). We are extremely excited to welcome you into the family.
