As your baby gains weight, he or she is also adding layers of fat. From now until about your 37th week of pregnancy baby will gain about a half-pound a week. The baby may also begin practicing breathing movements this week by moving his or her diaphragm in a repeating rhythm. These movements may give your baby a case of hiccups. As your baby continues to make these movements, you may occasionally notice a slight twitching in your uterus from baby’s hiccups. It may feel like little spasms.
You will feel larger and clumsier now and your movements will be slower. It is important to try to maintain good posture to prevent backache. You may have problems sleeping and become a bit breathless it you walk too last or climb stairs.
The baby is beginning to move about less vigorously now because it has less space to move around in the uterus. To get comfortable it is likely to adopt a curled-up position with arms and legs crossed. The baby is now about 15.7 inches (39,9cm) long and weighs around 2.9 pounds (1320 grams)
