The weight of your twins by the time of birth may reach 3.4 kg and their height will be about 51 cm. Of course, the weight between 2.5 kg and 3.8 kg is considered normal. About half of twins are born at the end of the 36th week of pregnancy, which is considered normal for twins. All their body parts are perfected, although the lungs are the last to be perfected. One of the twins usually moves towards the pelvic cavity. Most of the downy hair that has covered their body since week 26 will fall out, and most of the cream-colored fatty substance that covered their body surface will also fall off, and your twins will swallow it. And these substances are stored together with other secretory substances in their intestines. And it will form the first stool after birth, which is called meconium. The amniotic fluid around them, which was clear at first, now becomes slightly cloudy. And the outer layer of their skin falls off and new skin appears. Painless uterine contractions (Braxton Hicks), which started in the last 2 months in one twin, are seen much earlier in twin pregnancies. The pressure of twin pregnancy makes the cervix open earlier and the mother is ready to give birth. Nails: Their fingernails and toenails are now long. Skin: Most of the fluffy hairs on their skin and also the fat cream substance that covered their body surface will fall and your baby will swallow them and excrete a dark colored substance called meconium with the first stool after birth. Uterus: Uterine contractions (Braxton Hicks) are now usually seen more often.
