From What to Expect:
Coming down to the wire, your baby weighs around seven to eight pounds and measures 19 to 21 inches. Those measurements won't change much from now on, but her brain is still growing at an astonishing rate, a pace that will continue for the first three years of life. Her pink skin has now turned whitish (even babies who'll eventually have darker skin appear whitish now — they haven't yet developed pigment). Her head may have dropped into your pelvis by now, which makes your breathing easier but walking harder.
