Week 17

Fetal development in pregnancy week 17:fetus in fourth month 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 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!
