Choke and spit milk
The baby's digestive system is underdeveloped and the sphincter of cardia is not functional. When lying down to feed, the milk in the stomach is easy to flow back, causing choking or spitting.
Ear canal inflammation and hearing development
After choking or spitting milk, milk is easy to pour into the external auditory canal, forming ear canal inflammation and affecting hearing. Moreover, lying and feeding will increase the pressure on the baby's middle ear and affect the baby's hearing development.
Abnormal face
Lying down to feed, the baby's lower lip will work harder, the lower jaw will stretch forward and suck, and the lower jaw will stretch forward excessively. After a long time, abnormal face shapes such as "covering the sky and covering the sun" and "crescent face" may appear.
decayed tooth
After the baby's deciduous teeth erupt, if the baby falls asleep while drinking milk, the milk in the mouth will rot, produce acid and corrode the baby's teeth. Over time, it is easy to form dental caries.
It is healthier to sit and feed.
For the baby's health, try to feed in a sitting position.
