Occasional alternating hard and watery stools at 18 months can happen, but if this becomes a regular pattern, an underlying cause should be considered.
The most common cause is overflow incontinence from constipation: The child holds stool for a few days, creating a hard blockage in the bowel; watery stool accumulates behind this blockage and leaks out around it, appearing loose and uncontrolled. Parents often mistake this for diarrhea when the real problem is constipation.
Other possibilities:
- Dietary transitions (imbalanced high-fiber food and juice, excess milk/lactose)
- Irritable bowel syndrome-like disorder
Sound advice: Bring this information to your child's doctor:
1. How long the hard-watery cycle has been happening
2. Whether it's accompanied by stomach pain, gas, or fussiness
3. Diet (milk amount, fiber, fluids)
4. Whether straining or crying occurs during bowel movements
With exam and possibly abdominal imaging, constipation can be confirmed; treatment can often be resolved with simple adjustments.
