Week 32 of Pregnancy: Fetal Immune System

This week sweetpea is anywhere between 17 to 19 inches in length and weighs more than four pounds! He could grow a full inch more this week alone, and his weight can double before the big debut!
The level of amniotic fluid in my uterus has reached its maximum level, making it likely that I have more baby than fluid now. That's one reason why I've been feeling lots of nudges and pushes — there's less liquid to cushion the blows.
If my uterine walls had eyes, here's what we'd see: sweetpea acting more and more like a baby, with his eyes closing during sleep and opening while awake. And because those uterine walls are becoming thinner, more light penetrates the womb, helping him differentiate between day and night (now if only he can remember that difference on the outside!).
And good news! He has reached an important milestone about now: The development of his own immune system that (along with antibodies from me) will be able to provide protection from mild infections.
