Your Baby

Your baby is not much longer than 1 inch now, measuring from crown to rump; about the same size as a large green grape. Your baby weighs close to 2 grams this week, but may be going through another growth spurt towards the end of the week. Your baby will more than double his or her weight over the next several days. Your baby’s rapid growth rate is amazing! In addition to your baby’s overall growth, the cells which will become either testes or ovaries are creating the internal reproductive organs now. External genitals still don’t have noticeable male or female characteristics, yet, so your baby’s gender cannot be determined if you have an ultrasound.

Even though you can’t tell if your baby is a boy or a girl by viewing images on an ultrasound monitor at this stage of pregnancy, you most likely would be surprised to see him or her moving around and kicking! Your tiny baby’s movements my already be visible, if you have an ultrasound exam, because he or she is so very active. It’s a bit too early to feel your baby’s activity, but if you were able to touch him or her at this point; it would cause a reaction. Your baby would respond by turning away.

The major internal organs, muscles and nerves are continuing their growth and development. Your baby’s diaphragm is forming now, which is a muscle that separates the chest from the abdomen. The diaphragm enables your baby to breathe. Your baby’s intestines are growing longer and the digestive system is refining. Your little one’s fingers and toes have appeared and are in the process of taking their final shape. They are quite obvious, even though the hands and feet still look more like paddles than anything else.

Your baby’s torso is straightening and lengthening and the embryonic “tail”, which is located at the bottom of his or her spinal cord, is disappearing as well. Your little one’s body is becoming distinctly human in shape, although his or her head is still bent forward onto the chest and quite large compared to the rest of the body. The tiny face is becoming more rounded and is taking on a more mature appearance, as your baby gradually begins to look more like a baby now. Your baby’s eyes are fully developed and are covered by a thin membrane, which protects them. This membrane covering is actually the eyelids, but they are fused completely shut, until later in development (towards the end of the second trimester).
