How does the baby grow?
At this time the baby weighs about 1.1kg and is more than 38cm long from head to heel. The baby’s muscles and lungs are continuing to grow, and his or her head is also growing bigger for the brain to grow. To meet the growing nutritional needs, moms need lots of protein, vitamin C, folic acid, and iron. And because the baby’s bones are absorbing a lot of calcium, moms should drink milk (or look for other calcium sources like cheese, yogurt, or orange juice supplemented with calcium). In these three months, about 250mg of calcium is absorbed for the baby’s skeleton to be stronger gradually.
Changes occurring in the mother’s body during the 29th week of pregnancy
Some old symptoms – heartburn and constipation – may now return. Pregnancy progesterone dilates smooth muscle tissue throughout the body, including those in the digestive tract. Muscle relaxation, along with eating more, slows down digestion. Slow digestion can cause bloating and heartburn – especially after a large meal – and contribute to constipation.
The growing uterus also contributes to hemorrhoids. Swollen blood vessels in the rectum area are common during pregnancy. Fortunately, they usually disappear within weeks after giving birth.
Besides, some women have “supine hypotension syndrome” during pregnancy. This happens when lying on the back causes changes in heartbeat and blood pressure, causing dizziness until moms change positions. Moms may also feel dizzy when standing up too quickly. In this case, moms should lie on one side instead of lying on the back and move slowly from lying to sitting and getting up.
