An 8-month-old baby experiencing dry and difficult bowel movements may be due to insufficient water intake or poor digestion. If it is caused by inadequate hydration, parents can promptly increase the baby's fluid intake by offering more warm water to alleviate the symptoms. If the issue stems from poor digestion, parents should follow medical advice to administer digestive aids, such as lactobacillus granules, and may also use probiotics as supplementary treatment, for example, bifidobacterium triple viable powder.
