How our baby’s doing:
At 4 1/2 inches long (head to bottom) and 3 1/2 ounces, your baby is about the size of an avocado. In the next three weeks, she’ll go through a tremendous growth spurt, though, doubling her weight and adding inches to her length. Her lower limbs are much more developed now. Her head is more erect than it has been, and her eyes have moved toward the front of her head. Your baby’s ears are close to their final position, too. Some of her more advanced body systems are working, including her circulatory system and urinary tract. Her heart is now pumping about 25 quarts of blood each day, circulating her total blood volume through her body many times. (By the end of your pregnancy, this will increase to about 190 quarts.) The patterning of her scalp has begun, though her hair isn’t recognizable yet. Although closed, her eyes are moving (slowly), and she’s even started growing toenails.
Our baby’s development this coming week:
Don’t be too shocked but… your baby is EVEN bigger than it was last week, not to mention getting cuter, and smarter every day! As you’ve come to expect, there’s no shortage of growth and development this week: your fantastic little bean stalk has added yet another half inch to their overall height– making them nearly half a foot long! Their little limbs have reached (or are within one week of) their relative proportions, and will continue to grow evenly with the rest of the body after this week. Reactive listening has begun for your baby, even though their ears are not yet structurally complete or fully functional. Meanwhile, different parts of their astonishingly complex brain are developing to process your little one’s hearing and other senses, (you know, sight, smell, taste and touch). Mind boggling factoid of the week: if you’re having going to have a little girl, her ovaries have already produced millions of primordial egg cells, which, within a few weeks, will develop into actual eggs! Phew… just wait till she’s a teenager eh?
