Baby Diarrhea vs Loose Stool: How to Tell & Prevent Dehydration
Baby stool is normally softer than adult stool, making it difficult to determine if it's diarrhea. Learn the definition of baby diarrhea, its causes, home care tips, and when to see a doctor.
What Is Baby Diarrhea?
Normal baby stool can be loose, making diarrhea difficult to identify. Use these criteria to distinguish diarrhea.
Definition of Diarrhea
- Significantly more frequent than usual
- Much looser or watery than usual
- Enough to leak outside the diaper
- Different smell (more foul)
Normal Stool Reference
| Feeding Type | Normal Frequency | Normal Appearance |
|---|---|---|
| Breastfed | 6-10 times/day or once every few days | Yellow, seedy, loose |
| Formula-fed | 1-4 times/day | Tan/brown, toothpaste consistency |
| After Starting Solids | 1-2 times/day | Becomes similar to adult stool |
Common Causes of Baby Diarrhea
Infectious Causes
1. Viral Infection
Most common cause, including rotavirus and norovirus.

- May have vomiting, fever
- Lasts about 3-7 days
2. Bacterial Infection
Caused by salmonella, E. coli, etc.

Non-Infectious Causes
3. Food Allergy/Intolerance

4. Diet Changes

3. Skin Care
