How test tube babies adapt to the external environment in 40 days
IVF babies are cultivated in the laboratory through in vitro fertilization technology, and need to adapt to the new external environment after birth. The adaptation of test tube babies after 40 days can be described in detail from the following aspects.

Physiological adaptation
After 40 days of birth, the physiological function of IVF has basically developed. They can breathe autonomously, and the surfactant in the baby's lungs is sufficient to ensure normal breathing. In addition, their digestive system is well developed, which can digest and absorb nutrients in milk and excrete waste. During this period, the baby's skin gradually adapts to the external environment, starts to produce sebum, forms a protective layer, and strengthens the skin barrier function.
At the same time, the baby's physical function is also developing and can adapt to the changes in external temperature. In the hospital, especially in the neonatal ward, appropriate temperature will be provided to help infants adapt quickly and gradually increase the room temperature so that infants can gradually adapt to a wider temperature range.
In conclusion, after 40 days, IVF babies have basically reached the same physiological adaptation as naturally born babies.
Exercise adaptation
After 40 days of IVF, their motor ability gradually increased. In the hospital, infants will receive observation and guidance from medical staff to promote their exercise. For example, it can help infants develop motor skills through hand movement, head lifting, limb twisting, etc.
In addition, moderate massage is also helpful to the development of infants' sports. Massage can promote blood circulation, strengthen muscle strength, and cultivate the baby's movement coordination. The professional infant nurse in the hospital will carry out scientific massage therapy to help test tube babies adapt to the external environment.
In conclusion, through exercise and massage, IVF can gradually adapt to the external environment after 40 days.
Perceptual adaptation
After 40 days of birth, IVF babies began to perceive the external environment through various senses. In the hospital, medical staff will stimulate the baby's perception through voice, touch, vision and other ways. When babies hear nursery rhymes, mother's voice, etc., they can feel the temperature and texture of the outside world through touch, observe the facial expressions of medical staff, and gradually become familiar with different feelings.
At the same time, the sensory adaptation of IVF also includes the adaptation to light. In the lighting environment of the hospital, the light gradually increases, helping the baby's visual system develop gradually. The medical staff will also gradually adapt the baby to the external light and visual stimulation through the visual stimulation of the baby, such as the observation of mobile toys, black and white patterns, etc.
In general, the perceived adaptation of IVF infants after 40 days is achieved through hospital stimulation and environmental regulation. The baby gradually becomes familiar with different feelings, which helps to adapt to the external environment.
Emotional adaptation
After 40 days of IVF, they began to interact with their parents and establish close emotional ties. The neonatal ward of the hospital provides a safe and stable environment for parents and babies to have more opportunities to contact and communicate.
During the nursing period, parents can interact with the baby by hugging, pacifying, naming and other ways to strengthen the emotional bond between parents and children. The hospital also encourages parents to participate in baby care, such as diaper changing and feeding, to further strengthen the emotional relationship between the two sides.
Through the care of parents and medical staff, IVF can gradually adapt to and establish a close relationship with their relatives after 40 days.
summary
Test tube babies gradually adapt to the external environment, including physiological, motor, sensory and emotional adaptation, 40 days after birth. The hospital provides appropriate temperature, stimulation and care to help infants develop normally and adapt to changes in the outside world. In this process, infants are not only adapting to the environment, but also building emotional ties with their parents, laying a good foundation for future growth.
