Weeks 17 and 18

I'm behind, again! Here's what's been happening with baby!

Week 17:

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?

Week 18

We have two more ounces! Your "getting bigger-n-better by the minute baby" is already up to 7 ounces and 6 inches! This is a big week for their baby skin. There are now two distinct layers—the epidermis (or the surface skin) and dermis. Currently, their skin is covered with a greasy, waxy, cheese-like substance, known as vernix caseosa. Sure, it sounds pretty nasty, but this mixture of fatty secretions covering your little swimmer from head to toe is the best way to protect their oh-so-thin skin from bruising and abrasions as well as chapping caused by amniotic fluid exposure (and your little one is swimming in that stuff!). Still don’t like the fact your little darling is currently slathered in fatty cream like a greased pig? That adorable little greased piglet would have a lot harder time getting through the birth canal without the vernix caseosa. Fun fact for mommas with baby girls: it’s a uterus within a uterus! Your little girl will have developed a uterus and vagina canal by the end of this week.
