Health problems of test tube babies after 28 days
IVF refers to the embryo transferred to the mother's uterus after in vitro fertilization, also known as assisted reproductive technology baby. IVF babies need to pay special attention to their health after birth, especially in the first 28 days after birth. During this period, the newborn's body is still in the stage of development and adaptation to the environment. The following article will elaborate on the health problems of test tube babies after 28 days from several aspects.

Nutrition intake
In the earliest stage of IVF, nutrition is crucial to its healthy development. After 28 days, breast milk or formula is the main source of nutrition. Breastfeeding is the best choice. It provides rich nutrition and antibodies. Mothers need to maintain a good diet and take in enough vitamins, proteins and other nutrients to ensure the quality of milk. If breastfeeding is not possible, infant formula is an appropriate alternative. When choosing milk powder, doctors should be consulted according to the age and special needs of the baby.
The dietary needs of infants change with growth, so after 28 days, complementary foods should be introduced according to the doctor's advice. The first complementary food should be a single pure food, such as rice flour or paste food. Gradually introduce new foods, observe infants' responses to various foods, and ensure balanced nutrition. Parents should consult doctors in a timely manner to understand the nutrition and food required by the baby at each stage.
Immunization
Immunization is one of the important measures to ensure the health of infants. After 28 days, the baby can start vaccination to prevent some important diseases. According to the local immunization procedures, parents should consult the doctor to develop a vaccination plan suitable for infants. Common vaccines include DPT, poliomyelitis, hepatitis B vaccine and Haemophilus influenzae type B vaccine.
After vaccination, the baby may have some minor side effects, such as fever or swelling at the injection site. These reactions are usually normal and don't worry too much. If the side effect lasts for a long time or serious discomfort occurs, consult a doctor in time.
growth and development
After 28 days of IVF, growth and development is one of the key indicators that need careful observation. Parents should pay attention to the changes of baby's weight, height, head circumference and other parameters. In the first few months after birth, the baby's weight increases rapidly. If the baby's weight growth is slow or there are other abnormalities, the doctor should be consulted and checked in a timely manner.
In addition to weight, the baby's motor development also needs attention. After 28 days, the baby began to have more head control, and could look up and observe the surrounding environment. If the baby has obvious growth retardation or unusual movements, parents should consult a doctor in time.
Psychological and emotional development
The psychological and emotional development of infants is also very important in the 28 days after birth. Close interaction with parents and other caregivers helps to establish a sense of security and emotional connection. Kissing, cuddling and pacifying babies are crucial to their emotional development. Parents should try to reduce the contact between babies and electronic devices, and give them enough attention and companionship.
In addition, the baby's sleep habits should also be concerned. After 28 days, the baby began to have a more regular sleep cycle, but still needed more sleep time. Parents should provide a quiet and comfortable sleeping environment for infants and ensure adequate sleep time.
Summary
After 28 days, IVF infants should pay special attention to nutrition intake, immunization, growth and development, and psychological and emotional development. Reasonable diet and immunization will help babies grow up healthily. At the same time, the growth and development of infants as well as the development of their psychological emotions should be closely observed and concerned. Parents should consult doctors in time for guidance and support.
