Your baby now weighs more than 600g. She is starting to fill the space in your uterus (womb). From crown to heel she could measure 30cm. Though your baby still has little body fat and her skin is thin and fragile, she's well-proportioned. Her brain is growing rapidly, tastebuds have fully developed, and her footprints and fingerprints are continuing to form. Inside her body, her lungs are developing branches of the respiratory tree as well as cells that produce surfactant. This substance will help her air sacs inflate once she reaches the outside world.

Your baby weighs more than a pound and a half right now and sports a crown-to-rump length of about eight and a half inches (standard letter size!).
Wondering what (and who) your baby will look like? If you had a baby cam at 24 weeks pregnant, you'd almost be able to tell by now. That beautiful face (though still tiny) is almost fully formed. What's still missing from the picture is the fat that will be piled on under baby's skin. Until those fat deposits are made, that very tender skin is still very transparent, which means a close look would let you see clear through to all the organs, bones, and blood vessels. Fortunately, that see-through look won't last much longer. Babies at this stage of fetal development are gaining about six ounces each week — with much of that gain coming from fat, in addition to growing organs, bones, and muscle.
What's been playing on your little rocker's stereo system these days? All kinds of sounds can be heard by your baby in your womb: from air exhaling from your lungs (deep breath now), those gastric gurgles produced by your stomach and intestines, your voice and your partner's (which your baby will be able to recognize at birth), and even very loud sounds such as honking horns, barking dogs, or a wailing fire truck.
