Ice-cream for children does not usually cause constipation. The causes of constipation in children are commonly due to insufficient dietary fiber and water intake, poor bowel habits, excessive calcium supplementation, food allergies, etc. Ice-cream, however, is not a major daily food source. Ice-cream is mainly composed of water, buttermilk, sugar, etc., and is not a major daily food source, and generally does not cause constipation, but if parents observe an association between ice-cream and constipation, food allergies cannot be ruled out. When the child is constipated, the main focus is to improve the lifestyle and develop a bowel regularity, daily reasonable diet structure, increase the intake of fresh vegetables and fruits, increase the amount of water intake, and appropriate exercise, which can promote intestinal peristalsis and relieve constipation. If the baby can not relieve constipation through lifestyle improvement, it is necessary to consult a doctor to identify the cause of the disease.
