Respect natural development and avoid unnecessary interference
15 days after birth, the IVF baby is in the early stage of life, and its immune system is not fully developed, so it is vulnerable to external pathogens. At this stage, parents should respect the natural development process, avoid excessive intervention, and let the baby establish immunity independently.

First, avoid using too many disinfectants and detergents. The skin of IVF is delicate and sensitive. Over disinfection may damage the skin defense barrier, but it is easy to cause infection. Proper cleaning and moisturizing is a better choice. Take a bath with warm water and use special baby skin care products to keep your skin clean and tidy.
Secondly, keep moderate temperature and humidity indoors. IVF is vulnerable to temperature and humidity, and too high or too low temperature may have a negative impact on the immune system. At home, reasonably adjust the room temperature, keep the air circulation, and avoid excessive drying or humidity.
Finally, do not touch the outside environment too early. The immune system of test tube babies is not fully developed, and their resistance to external bacteria, viruses and other pathogens is weak. Therefore, within 15 days, try to reduce the risk of infection by taking babies out and avoiding exposing them to public places and crowded places.
Scientific feeding and balanced nutrition guarantee
The immunity of IVF is closely related to its diet and nutrition intake. In the process of improving the immunity of test tube babies after 15 days, scientific feeding is an important guarantee.
First, breastfeeding is the best choice. Human milk is rich in antibodies and immunoglobulins, which play an important role in the development of infants' immune system and can effectively prevent and alleviate infection. Therefore, if conditions permit, it is recommended to breastfeed and pay attention to maintaining good breast milk secretion.
Secondly, if breast-feeding is not possible, appropriate formula should be selected and formulated and fed in strict accordance with the product instructions. At the same time, attention should be paid to avoid adding complementary foods too early, so as not to burden the infant's digestive system and immune system.
Finally, pay attention to the nutritional balance of food. Reasonably choose foods rich in protein, vitamins and minerals, such as meat, vegetables, fruits, etc., to promote the nutrition absorption and immune enhancement of infants.
Keep good living habits
Good living habits are also important for improving the immunity of IVF. After 15 days, parents should cultivate the baby's good living habits.
First, regular physical examination and vaccination. Take the baby to a regular hospital for physical examination in time, check potential health problems, and vaccinate according to the doctor's recommendations. Vaccines can help infants establish immunity to specific pathogens and provide additional protection.
Secondly, keep moderate exercise and rest. Proper exercise can enhance the baby's physique and immunity, but excessive exercise will make the baby tired and weaken the immune system. Therefore, exercise and rest time should be reasonably arranged according to the age and growth of the baby.
Finally, careful nursing can help infants establish good living habits. Adequate and regular sleep, regular replacement and cleaning of baby clothes and bedding, and keeping the indoor air fresh and clean are all helpful to keep babies healthy and improve their immunity.
Good maintenance of family environment
In order to improve the immunity of IVF, we should also pay attention to the good maintenance of the family environment.
First, keep the indoor air fresh. Ventilate regularly to avoid the pollution of second-hand smoke and harmful gases, and keep the indoor air clean and healthy.
Secondly, keep the interior clean. The cleanliness of the home is very important for the health of infants. Regularly clean and disinfect the toys, baby bottles and other items of infants to ensure that the items contacted by infants are clean and sterile.
Finally, avoid the pollution of harmful substances. Building materials, paints and furniture at home may contain harmful substances such as formaldehyde, so green and environmentally friendly products should be selected to avoid potential risks to the health of infants.
By respecting natural development, scientific feeding, good living habits and good maintenance of family environment, IVF's immunity after 15 days has been effectively improved. Parents should always pay attention to the health and development of the baby, seek medical advice and consult professionals in time, and protect the baby's immune system in an all-round way so that it can thrive.
