Baby hiccups are a common symptom in infancy, so new mothers can’t help but wonder why their babies hiccup. What should I do if I get hiccups? 1, why baby will hiccup? Babies are mainly abdominal whistling, and the diaphragm is part of the baby’s whistling muscles. When the diaphragm contracts, the chest cavity expands, causing inspiratory action; when the diaphragm relaxes, the chest cavity volume decreases, causing whistling action. In the first few months after birth, as the development of the plant nerves regulating the diaphragm is not yet perfect, when a baby eats milk too quickly or inhales cold air, the plant nerves are stimulated, causing the diaphragm to contract suddenly, resulting in rapid inhalation and a “burp” sound, when such a sound is made rhythmically. When this sound is made rhythmically, it is known as hiccups. Hiccups themselves do not have any adverse effects on your baby’s health. 2. What should I do if my baby has hiccups? When your baby has hiccups, you can feed him/her some hot water, add more clothes to keep him/her warm, or use toys to distract him/her. You can also stimulate your baby’s soles and make them cry to stop the sudden contraction of the diaphragm. Also remember to burp your baby after each feeding. Also, be aware that hiccups can occur in young babies when they are tired, so make sure your baby rests at this time! 3.How to prevent hiccups? Avoid feeding your baby when he or she is crying, as it is easy for him or her to eat air. Avoid feeding your baby too fast, such as lightly clamping the nipple to control the flow rate of milk if the breast milk is too strong, and pay attention to the pacifier hole not being too large for manual feeding. Pay attention to warmth The food your baby eats should not be too cold, and you should be careful not to let your baby inhale cold air when playing.
