Babies, especially newborn babies, are prone to spitting up, and the most fearful thing about spitting up is that when milk flows backwards from the esophagus to the throat, it accidentally enters the trachea at the moment of inhalation, i.e. choking. Choking can easily lead to choking and pneumonia, which can even be life-threatening. First, how to deal with first found vomiting milk, you should quickly turn the baby’s face to the side, so as not to spit backward into the throat and trachea, let it lie prone on the bed, forcefully pat the back four or five times, so that the baby can cough out the milk. If it is still ineffective, immediately clip or pinch to stimulate the sole of the baby’s foot to make the baby cry due to pain and increase breathing. The most important thing at this time is to let him take in oxygen into the lungs rather than wasting time thinking about how to get the foreign body out. During the above process, the baby should be taken to the hospital for examination at the same time. If the baby is breathing well after choking, it is best to find a way to make him cry harder to observe the oxygen intake and exhalation action when crying to see if there are any abnormalities, such as the voice becomes toned and weak, inspiratory difficulties, severe concave chest, etc., if there should be immediately sent to the hospital. If the baby cries brightly, with a full breath and a rosy face, it means there is no serious problem. How to prevent 1. Proper timing of breastfeeding: do not breastfeed when the baby is crying or laughing; do not wait until the baby is very hungry, the baby is too eager to eat and easily choke; the child is full and cannot be forced to feed again, force feeding is prone to accidents. 2, correct posture: breastfeeding baby should lie in the mother’s arms (upper body into 30-45 degrees), do not lie on the bed feeding. Manual feeding babies should not lie flat when feeding, but should take a sloping position, with the bottom of the bottle higher than the nipple to prevent air inhalation. 3. Control the speed: When the mother is lactating too fast and the amount of milk is too much, use your fingers to lightly press the areola to slow down the flow of milk. The nipple hole for manual breastfeeding should not be too large, and the milk should flow out in drops rather than in lines when you pour it over. 4. Pay attention to observation: the mother’s breast should not block the baby’s nostrils. Be sure to observe the baby’s face and expression while breastfeeding. For babies who have choked or premature babies, you should observe them closely or ask your doctor for guidance on feeding. 5. Expel gas from the stomach: After feeding, hold the baby upright on your shoulder and pat the baby’s back to help expel gas from the stomach, it is best to hear burping and then put the baby in bed. The head of the bed should be 15 degrees higher, lie on the right side for 30 minutes, and then lie flat. Do not let the child sleep on his or her back to avoid sudden death of the infant.
