Your baby can be anywhere between 16 and 17 or more inches in length and they could grow upto another full inch this week, especially if they've been on the shorter side.

The little one weighs more than 4½ pounds and is still gaining weight at a rate of about half a pound a week. Weight gain can range from a third more to a full doubling.

When your baby is inside your uterus, your amniotic fluid level has maxed kit at 33 weeks of pregnancy, makes it likely that you have more baby than fluid now. This is why some of their pokes and kicks are felt pretty sharp.

If you’re uterus had eyes it would see that your fetus is acting more and more like a baby whith thier eyes closing during sleep and open while being awake.

And this happens because the uterus walls are becoming thinner, and that's why light passes through to the womb which helps the baby differentiate between day and night.

Your baby has reached an important milestone, they have got their immunity system. Antibodies are now being passes from you to your little one as they continue to develop their fetal immune system, which will come in handy as they come outside the womb and fending off all kinds of germs.
