The common reasons why babies get hiccups when they eat a little milk are: 1. Due to poor care of the baby, when wind chill occurs, indoor temperature is too low or after being blown by the wind, the baby inhales cold air while eating milk will also induce hiccups, you can give the baby some hot water properly, while covering the chest and abdomen with quilts, if it is winter you can also put a small hot water bag outside the jacket for insulation, after a while it will not hiccup. 2. Feeding If the baby is too fast or frightened when feeding, he or she will burp when crying, so try to keep the surroundings quiet and comfortable when feeding, and try to speak quietly so as not to frighten the baby.4 If your baby is not digesting, he or she will also have hiccups when eating a little milk, accompanied by a thick tongue and hiccups that can smell sour.
