What “Stomach Flu” Really Means
Most toddler tummy bugs are viral gastroenteritis—often from rotavirus, norovirus, or adenovirus. While usually self‑limited (48–72 hours), watery diarrhea and vomiting can drain body water fast. The Centers for Disease Control and Prevention lists dehydration as the top complication sending toddlers to the ER . A solid home plan keeps electrolytes balanced and flags danger early.
Signs Your Toddler Has Viral Gastroenteritis
| Early Clues | Typical Timeline | What to Watch |
| Sudden vomiting | Day 1 | Frequency, persistence |
| Watery diarrhea | Day 1–3 | Number of stools (track) |
| Low‑grade fever (100–101 °F / 37.8–38.3 °C) | Day 1 | Fever > 102 °F suggests doctor visit |
| Appetite drop | Whole course | Offer fluids first |
Bloody stool or severe abdominal pain points to bacterial infection—schedule a same‑day exam.
Hydration Plan: The 30‑60‑90 Rule
30 ml (1 oz) oral‑rehydration solution (ORS) every
60 minutes for 90 minutes. If no vomiting after three doses, double to 2 oz hourly. Use pedialyte‑style ORS—balanced electrolytes trump plain water, which dilutes sodium.
Homemade ORS Recipe
1 qt (950 ml) clean water + ½ tsp salt + 6 tsp sugar + ½ cup OJ or mashed banana for potassium. Stir until dissolved.
“BRAT” Diet—Updated and Expanded
| Food | Why It Works | Serving Tip |
| Bananas | Potassium replaces losses | Mash into 1‑tbsp portions |
| Rice (white) | Easy‑digest starch | Add pinch of salt |
| Applesauce | Pectin firms stool | Unsweetened cups |
| Toast | Bland carbs | Avoid butter first 24 hrs |
| PLUS: Plain yogurt | Probiotics aid gut recovery | Choose live cultures |
| Soft‑scrambled egg | Protein for healing | Introduce after 24 hrs vomit‑free |
Skip juice and sports drinks; fructose and high sodium worsen diarrhea.

Red‑Flag Dehydration Signs—Call Us Fast
- Fewer than 4 wet diapers in 24 hrs (or no pee in 8 hrs)
- Sunken eyes or fontanelle
- Dry mouth, no tears when crying
- Lethargy or floppy limbs
- Rapid breathing or heart rate
- Vomit or diarrhea streaked with blood
Call for dehydration assessment—our nurses can test skin turgor, capillary refill, and, if needed, arrange IV fluids.
Medication Guide (Less Is More)
| Symptom | Safe Option | Age Note |
| Fever > 102 °F (38.9 °C) | Acetaminophen 15 mg/kg q4–6 hrs | ≥ 3 months |
| Vomiting (persistent) | Ondansetron ODT (Rx only) | Pediatrician approval |
| Diarrhea | No loperamide | Risk of toxic megacolon |
Never give aspirin—Reye’s syndrome risk in viral illnesses.
Cleaning & Containment Tips
- Bleach solution (1 Tbsp bleach : 1 gal water) on toilets, sinks, and toys. Norovirus survives alcohol wipes.
- Separate laundry: hot wash > 60 °C; wear gloves handling soiled clothes.
- Hand‑wash with soap 20 s; sanitizers are less effective on vomit particles.
- Keep siblings out of splash zone; viral particles aerosolize 15 ft after vomiting (yes, really).

Myth‑Busting Corner
Myth 1: “Starve the bug—no food for 24 hrs.”
Reality: The gut lining heals faster with small carbohydrate feeds; starvation extends diarrhea.
Myth 2: “Flat soda rehydrates.”
Reality: High sugar pulls water into intestines—worsening fluid loss.
Myth 3: “Antibiotics prevent complications.”
Reality: Viral illness; unnecessary antibiotics upset gut flora and can cause C. difficile.

Travel & Day‑Care Return Rules
| Condition | Home | Return When… |
| Vomiting | Stay | 24 hrs vomit‑free |
| Diarrhea | Stay | Stool formed or contained by diaper |
| Fever | Stay | 24 hrs fever‑free without meds |
Provide day‑care with a doctor’s clearance if symptoms were severe.
Sample 24‑Hour Recovery Log
| Time | Intake (ml) | Output | Notes |
| 7 a.m. | 30 ORS | Loose stool | |
| 10 a.m. | 60 ORS + 1 tbsp banana | Wet diaper | Mood improving |
| 1 p.m. | 60 ORS | Nap 1 hr | |
| 4 p.m. | 2 oz rice cereal | Wet + stool | |
| 7 p.m. | 2 oz plain yogurt | Wet diaper | Temp 99 °F |
| 10 p.m. | 30 ORS | — | Asleep |
Bring this to any follow‑up; trends trump single observations.

Bounce‑Back Timeline
| Day | Expectation |
| 1 | Frequent watery stools, vomiting |
| 2 | Vomit slows, appetite sparks |
| 3 | Diarrhea tapering, energy returns |

If diarrhea persists beyond a week, schedule a stool culture.
