From The Bump:
Your baby is the size of a coconut. Now, his hearing is fully developed, and he responds best to high-pitched noises.
From What to Expect:
At about 20 inches and five and a half pounds (but with about five more weeks to grow), most of your baby's growth over the next month or so before you meet will be in weight (with a gain of anywhere from one pound to several), not height (baby's pretty much reached the in utero limit in that department). Accordingly, fat continues to accumulate at a rapid pace these days (on baby, not just on your hips). Back in the middle of your pregnancy, your baby's weight was made up of only two percent fat; now at 35 weeks pregnant, that percentage has soared to closer to 15 percent (and will increase to 30 percent at term). Which means your baby's once skinny arms and legs are now quite plump…and irresistibly, squeezably soft.
Also continuing to grow at an amazing pace is your baby's brain power. Luckily, the part that surrounds that amazing brain — the skull — remains soft. And for good reason: A soft skull will allow your baby to squeeze more easily through the birth canal. (Mother Nature was really thinking this one through — imagine trying to push out a rock-hard head…ouch!)
From Giggle Glow:
Your baby is probably around 20 inches or so, which means she won't get much longer, but the baby fat is still accumulating (especially around the arms and legs) to help her regulate her body temperature in the outside world. At this point, your baby's physical development is mostly complete, and the last few weeks are mostly about plumping up — and when it comes to babies, plump means healthy!
