Your baby weighs about 1.5kg and looks more than ever like a newborn. He measures about 41cm from crown to toe. His arms, legs and body continue to fill out – and they are finally proportional in size to his head.
You may notice your baby isn't moving around as much. That's because he's just running out of space in your uterus (womb). As long as you can feel him squirming and kicking, you'll know he's just fine. Believe it or not, he still has plenty of growing to do. You can expect him to gain at least 900g before birth.
Your baby's organs are continuing to mature and he is passing water from his bladder, which is good practice for the weeing he'll do after he's born. Also, the marrow in his bones has taken over from his liver the job of producing red blood cells.

As far as growth goes, your baby's still on a roll, measuring an impressive 18 inches and weighing in at more than three pounds. At 31 weeks pregnant, you can still expect your baby to gain at least three to five pounds, possibly more, before you two meet.
Your baby's brain is working overtime these days, developing faster than ever. Connections between individual nerve cells are growing at a frenetic clip, and your baby can now perceive information from all five senses. Sure, your baby can't smell anything right now, but that's only because he or she is still submerged in amniotic fluid and needs to be breathing air to get a whiff of anything. Lucky for you — and your baby — yours will be one of the very first scents your baby breathes in, a scent that will quickly become his or her very favorite.
So what's your little dove doing all day while you're busy feathering your nest for his or her arrival? Making faces, hiccupping, swallowing, breathing, pedaling with little hands and feet along your uterine wall, and even sucking his or her thumb. In fact, some babies suck their thumbs so vigorously while in the womb that they're born with a callus on their thumb (what a little sucker!).

Your baby is putting down more fat stores underneath his skin and gains as much as 17 ounces per week. The hair that covers your baby’s skin, called lanugo is shedding slowly this week and will probably be gone by the time your baby is born. Some premature babies are still covered in hair, but this will soon shed. You probably won’t feel your baby moving quite so much now because it is getting more and more cramped inside your uterus. This is one of the reasons why twins usually come early.
Your baby may turn into a headown position soon in preparation for the birth. Most babies turn at around 28 to 32 weeks but some don't turn until the day they are born! It is much harder for breech babies (head up) to be born vaginally or without medical intervention which is why it is better for your baby to be facing head down. See our article and video about how to encourage your baby into a good position for birth. Your baby measures about 18 inches this week and probably weighs somewhere near 3.5 pounds. Having said that all babies are different sizes so it is very hard to predict what size your baby will be. If you measure small for dates, you will have got used (and annoyed) to people mentioning how small you seem and vice versa for women with large bumps. The best remedy is to ignore everybody! What matters is that you and your baby are healthy and that you will meet each other very soon.
