3d rendered medically accurate illustration of a fetus in week 31

The baby weighs at around 1.6 kgs and measures 16 inches long. He has almost approached his birth length but will add about 1 more kg before birth. His sleep cycles have increased. His brain is developing faster than ever. Neural connections are increasing rapidly, and he processes information from all five senses.

By now his kidneys work well, and he urinates a few cups of urine a day into the amniotic fluid. Please be wary of excess amniotic fluid (polyhydramnios) or inadequate fluid (oligohydramnios). These are medical conditions which your health provider can advise you on.

Your baby is getting larger and does not have much room in your uterus – hence his movements seem less frequent and forceful .His organs continue to mature and a layer of fat is being added under his skin. His muscle mass is increasing and his muscle tone is also improving.
