By the end of the 32nd week, each baby will weigh approximately four pounds. Actually, twins are tracking along the same rate as singletons at this point of the pregnancy. You should be familiar with their patterns of movement, although it is not as strong. It is difficult to determine which baby is which. Some moms can feel when their babies have the hiccups. This is very normal and should not be a concern. The babies are putting on alot of fat now, which is necessary after birth to regulate temperature. During this month, the head will be more in proportion to the body. With the exception of the lungs, all organs and systems are operational. At this point, fatigue is very pronounced. Listen to your body and rest when you can. Even if you can not actually sleep, try to prop your feet up and allow your body to rest. Breathlessness may also be worse now. Your uterus is taking up an incredible amount of room in your diaphragm. Sitting up straight may help some with this problem. Backache is becoming worse also. Pay attention to any new or unusual aching in your back-it could be a sign of preterm labor. A nice, warm bath can help soothe the discomfort of a backache. Do not sit in a jacuzzi or use hot water, though. If you spend alot of time standing up or sitting down, hemorrhoids are likely to be a problem. To avoid constipation that could make the hemorrhoids worse, continue to eat a balanced diet and drink plenty of water. Cold packs and sitz baths may offer some relief.
