Premature birth refers to delivery between 28 to 36 weeks plus 6 days of pregnancy. Due to the lower body weight and immature organ development of the fetus, premature birth can lead to decreased survival rates and increased morbidity in newborns. The signs of impending premature birth include the following aspects: First, the occurrence of regular contractions, which are the most common sign of premature birth. If intermittent lower abdominal pain occurs, it should be taken seriously, and fetal heart rate monitoring may be necessary for assessment. Second, the appearance of blood in the vaginal discharge often indicates that the fetal presenting part is descending, which is also a sign of premature birth. Third, a physical examination may reveal shortening of the cervical canal and dilation of the cervix, suggesting the possibility of premature birth. When these conditions occur, they should be taken seriously, and medication may be necessary for treatment. (Specific medications should be used under the guidance of a physician.)

Do frequent Braxton Hicks contractions lead to preterm labor?

In the late stages of pregnancy, there may be occurrences of Braxton Hicks contractions, generally happening at a low frequency of about two to three times per day. Some individuals experience these false contractions primarily at night, which disappear during the day. This is considered normal physiological behavior in the late stages of pregnancy. If there is a frequent occurrence of Braxton Hicks contractions, it may also lead to the dilation of the cervix, causing premature labor. Therefore, if this situation arises and the fetus is not yet full-term, it is recommended to go to the hospital for an examination in a timely manner, and symptomatic treatment to maintain the pregnancy may be necessary.

How to switch from preterm formula to regular formula?

Generally, in the early stages of preterm infants, it is still necessary to feed them promptly with preterm formula. Since the gastrointestinal function of preterm infants is relatively weak, they may not be able to digest and absorb some full-term formula, which can easily increase the burden on the gastrointestinal tract. If the baby's development is currently good, you can switch to ordinary formula. During the transition between two formula brands, there should first be a gradual shift; you can start by mixing the two formulas, using more preterm formula and less ordinary formula. Gradually switch to the new ordinary formula brand, reducing the amount of preterm formula, allowing the baby to adapt gradually.

What should I do if a premature baby spits up milk?

For premature babies who experience spitting up, first pay attention to the feeding position. During feeding, make sure to hold the baby up with their head higher than their buttocks, which facilitates the smooth passage of milk through the gastrointestinal tract. Additionally, if the baby vomits, first pick the baby up and gently pat their back to help release some of the residual gas in the stomach, which can reduce spitting up and vomiting. Also, during feeding, be mindful not to feed too much at once; feeding small amounts more frequently can also help prevent spitting up.

Preterm birth refers to how many weeks?

Premature birth refers to a baby born after the pregnancy has reached 28 weeks but before completing 37 weeks. Most of these babies weigh less than 2500 grams at birth and have poorer adaptive abilities compared to full-term babies. They require special care. Feeding premature infants can be challenging. They generally need to be fed breast milk or formula every two to four hours. Start by feeding once or twice; if there is no vomiting for six to eight hours, continue feeding some milk. Also, position the baby's head to one side to prevent inhalation of vomit.

What is the earliest month that premature birth can occur?

Under normal circumstances, the entire childbirth process for a fetus is divided into three stages: early pregnancy, middle pregnancy, and late pregnancy. Generally, fetal development between 28 to 40 weeks is considered a viable period. During this time, if delivery occurs, the baby's chances of survival are very high. However, normally, a fetus between 37 to 40 weeks is considered full-term, so babies born before 37 weeks are referred to as premature. Premature babies need close monitoring of their developmental status after a normal delivery to avoid potential complications.
