Now weighing about 3 pounds (1,400 grams) and measuring about 10.8 inches (27 cm) from crown to rump, your baby continues to gain weight and layers of fat. This fat makes the baby look less wrinkly and will help provide warmth after birth. In preparation for respiration after birth, your baby will mimic breathing movements by repeatedly moving the diaphragm. Your baby can even get the hiccups, which you may feel as rhythmic twitches in your uterus.
Constipation is a common complaint of pregnancy. The pregnancy hormones that allow you to maintain your pregnancy also slow the digestive process considerably. Exercising regularly and eating foods high in fiber, such as vegetables and whole grains, are great ways to keep everything regular.
