Common symptoms of test tube infants in 13 days
IVF refers to the embryo that is cultivated in the laboratory and transferred to the mother through in vitro fertilization technology. This technology has helped many infertile couples achieve a healthy baby. In the first few weeks after birth, IVF babies will show some special symptoms and characteristics. This article will elaborate on the symptoms of IVF after 13 days from the aspects of growth and development, sleep, diet and digestive system.

Growth and development
After 13 days of IVF, the growth and development of IVF proceeded rapidly. Infant weight gain is one of the most important concerns of parents. Generally speaking, IVF babies will gain weight in the first few weeks after birth. Because the gestational age of IVF is calculated from the date of embryo transfer, the gestational age is actually close to 3 weeks at 13 days. Therefore, at this stage, the weight will generally increase by 20-30 grams per day. In addition, after 13 days of IVF, the length and head circumference will also increase correspondingly.
At this time, the nervous system of IVF begins to develop, and the baby will become more active and sensitive. They began to be able to hold their fingers and often reached out to touch objects around them. They can also react to sounds and turn to the source of the sound. The baby's ability to respond to external stimuli has also gradually increased.
sleep
When IVF babies were 13 days old, sleep still occupied most of their time. Babies need about 16-18 hours of sleep every day. They often wake up in sleep, which is normal. Babies in this period did not develop a clear rhythm of day and night, so their sleep time and frequency were irregular. Therefore, parents don't need to worry too much about the sleeping condition of their babies, just give them enough rest time.
diet
At 13 days of IVF, feeding is still their main need. For breastfed infants, the duration of each feeding is generally 10-15 minutes. Breast milk contains rich nutrients, which are very important for the growth and development of infants. At the same time, parents can also choose formula feeding, and choose suitable milk powder for feeding under the guidance of doctors.
Please note that the feeding needs of each baby are different, and parents should judge whether they are satisfied according to the needs of the baby. During the feeding process, it is necessary to ensure that the baby is full and has correct body posture to avoid accidents such as choking.
digestive system
The baby's digestive system will gradually develop and improve within a few weeks after birth. By the 13th day of IVF, the digestive system has been able to absorb and digest food better. However, as the digestive system is not fully developed, infants are prone to abdominal flatulence and other problems. In order to alleviate the discomfort of abdominal distension, parents can help the baby exhaust by massaging the baby's abdomen, changing the feeding posture appropriately or giving some appropriate drugs under the guidance of the doctor.
In conclusion, after 13 days, IVF babies will show a series of characteristics and symptoms of normal growth, development, sleep, diet and digestive system. Parents should closely observe the changes of the baby and take corresponding nursing measures as needed. It is very important to keep communication and consultation with doctors to understand the growth and development of infants.
