Abdominal Pain (Tummy Ache) in Babies & Toddlers
Content reviewed against published AAP, AAP, NIH guidelines
Last reviewed:
Abdominal pain is one of the most common complaints in young children but also one of the most challenging to evaluate because babies and young toddlers cannot verbalize their symptoms. In infants, abdominal pain is usually indicated by drawing up legs, arching, inconsolable crying, or a distended belly. In verbal toddlers, tummy aches are extremely common and are most often caused by constipation, gas, viral illness, or non-specific functional pain. However, certain patterns of abdominal pain — particularly sudden severe pain, pain with vomiting, or pain localized to the right lower quadrant — require urgent evaluation.
Key takeaways
- Abdominal pain is one of the most common complaints in young children but also one of the most challenging to evaluate because babies and young toddlers cannot verbalize their symptoms.

- Home care: For gas pain in infants: bicycle legs, tummy massage, warm bath
Possible Causes
When to Seek Help
Emergency — Call 911 or go to ER:
- Severe abdominal pain with bilious (green) vomiting — possible volvulus
- Episodic severe pain with "currant jelly" stool and lethargy — possible intussusception
- Abdominal pain with distension, absent bowel sounds, and peritoneal signs (rigid abdomen)
- Abdominal pain with inguinal swelling that is hard and tender (incarcerated hernia)
- Severe pain with signs of shock (pale, rapid heartbeat, lethargic)
Urgent — See doctor today:
- Progressively worsening abdominal pain over several hours
- Pain migrating to right lower quadrant with fever (possible appendicitis)
- Abdominal pain with persistent vomiting and no stool output (possible obstruction)
- Abdominal pain with signs of dehydration
- Severe pain causing child to refuse to walk or move
Same-day appointment:

By Age
0-3 months
Normal: Colic (defined as crying more than 3 hours/day, more than 3 days/week, for more than 3 weeks) peaks at 6 weeks and resolves by 3-4 months. Gassy discomfort with leg pulling and straining is extremely common.
Worry if: Sudden-onset severe crying with pale color and drawing up legs in episodes (possible intussusception). Distended, firm abdomen. Bilious (green) vomiting with abdominal pain. Inguinal swelling (possible incarcerated hernia).
3-12 months
Normal: Brief episodes of fussiness from gas or dietary changes are common. Some discomfort with introduction of new foods is normal.
Worry if: Episodic severe pain (every 15-20 minutes) with screaming, pallor, and lethargy between episodes (classic intussusception pattern). Pain with bloody or "currant jelly" stool. Pain with distended abdomen and vomiting.
1-3 years
Normal: Frequent complaints of tummy aches are common in toddlers and are most often from constipation, gas, or anxiety. Pain that is brief, periumbilical (around belly button), and does not interfere with play is usually benign.
Worry if: Pain that wakes the child from sleep. Pain localized to right lower quadrant (possible appendicitis). Pain with fever, vomiting, and child not wanting to move. Pain progressively worsening over hours. Pain with unable to walk or bent over.
Home Care
- For gas pain in infants: bicycle legs, tummy massage, warm bath
- For constipation: increase fluid and fiber intake, prune or pear juice for babies over 6 months
- A warm (not hot) compress or warm bath can relax abdominal muscles
- Encourage rest in a comfortable position (many children prefer lying on their side with knees drawn up)
- Offer clear fluids in small amounts if nausea is present
- For toddlers: distraction often helps if pain is mild and functional
- Do NOT give laxatives without medical guidance in babies under 6 months
- Do NOT press on or massage a hard, distended abdomen
- Keep a pain diary (timing, relation to meals, stool pattern) if pain is recurrent
- If child cannot be distracted from pain or pain wakes from sleep, seek medical evaluation
