- 2. 6 Weeks 6 At 6 weeks (42 days) the baby’s nose, ears, and mouth begin to develop. Also, the baby’s heart rate is 100-160 beats per minute, twice as fast as the parent. Intestines are producing and blood is flowing through the fetus’ body.
- 3. 9 9 Weeks Nearly an inch long the fetus probably weighs about an ounce. The heart divides into four chambers and valves start to form and plus tiny teeth. Baby’s organs and muscles are forming and coming into place. Eyes are fully formed but would not be open until 27 weeks.
- 4. 13 Weeks The Baby is now a fetus, the eyes are formed and are fused together and her arms and legs begin to twitch and more. The baby is about the size of an egg and weighs about .5-.8 ounces.
- 5. 17 Weeks The fetus reaches a length of about 15 cm (6 inches). A fine hair called lanugo develops on the head. Fetal skin is almost transparent. More muscle tissue and bones have developed, and the bones become harder. The fetus makes active movements. Sex prediction by obstetric ultrasonography is almost 100% accurate. The main development of external genitalia is finished.
- 6. 21 Weeks The fetus reacts to loud sounds. Baby starts having a regular sleeping and waking rhythm. The mother's movements can wake her baby. Taste buds are forming on your baby's tongue. The baby is 28cm long (crown to heel) and weighs over 450 grams. The weekly weight gain has increased to around 70 grams.
