Bruising in Babies & Toddlers
Content reviewed against published AAP, NICE, CDC guidelines
Last reviewed:
Bruises (contusions) occur when blood vessels under the skin break from impact. In mobile toddlers, shin and forehead bruises are common from falls. However, bruising in pre-mobile infants (before crawling/cruising) is unusual and warrants medical evaluation. The mnemonic "those who don't cruise rarely bruise" is a key clinical principle — any bruising in a baby who is not yet pulling to stand should be assessed.
Key takeaways
- Bruises (contusions) occur when blood vessels under the skin break from impact.
- Most common cause: Normal childhood bumps and falls (mobile toddlers)
- Emergency: Any bruising in a non-mobile infant (cannot yet pull to stand)
- Home care: Apply a cold compress or ice wrapped in cloth for 10-15 minutes to reduce swelling after injury
Possible Causes
When to Seek Help
Emergency — Call 911 or go to ER:
- Any bruising in a non-mobile infant (cannot yet pull to stand)
- Bruising with signs of head injury (vomiting, unresponsive, seizure)
- Widespread sudden bruising with bleeding from gums, nose, or in stools
- Bruising with very high fever and child appearing extremely unwell (sepsis)
Urgent — See doctor today:
- Multiple unexplained bruises in unusual locations at any age
- Bruising with pallor, fatigue, weight loss, or enlarged lymph nodes
- Easy bruising with a family history of bleeding disorders
- Patterned bruising or bruising in shapes inconsistent with accidental injury
- Bruising with petechiae (pinpoint non-blanching spots)
Same-day appointment:
- New onset of easy bruising — bruising more than usual for activity level
- Large bruise from relatively minor impact (may indicate bleeding disorder)
- Bruising with frequent nosebleeds or prolonged bleeding from cuts
- Parent concerned about pattern or frequency of bruises
Monitor at home:
- Typical shin and forehead bruises in an active toddler
- Single bruise with clear accidental cause in a mobile child
- Mongolian spots (blue-grey flat patches present from birth)
- Bruise healing normally through expected color changes
By Age
0-2 months
Normal: Mongolian spots (blue-grey flat patches on buttocks/back) are normal pigmentation, not bruises. Birth-related bruising (from forceps, vacuum extraction) resolves within 1-2 weeks. Some petechiae on face from birth is normal.
Worry if: ANY unexplained bruising in a non-mobile infant is concerning and needs evaluation. Bruising in unusual locations (ears, neck, trunk, buttocks). Bruising with bleeding from other sites. Bruising with no clear mechanical explanation.
2-6 months
Normal: Babies at this age are typically not yet mobile enough to bruise themselves. Mongolian spots are still present.
Worry if: ANY bruising in a pre-mobile infant requires medical assessment. Bruising in patterned shapes (hand prints, loop marks, grab marks). Multiple bruises at different stages of healing. Bruising with poor weight gain or other concerns.
6-12 months
Normal: Once cruising and pulling to stand (typically 8-10 months+), forehead and shin bruises from falls become common and expected. Bruises over bony prominences (forehead, shins, knees) are typical.
Worry if: Bruising in a baby not yet cruising/pulling to stand. Bruises on soft tissue areas (cheeks, ears, neck, trunk, buttocks). Excessive bruising disproportionate to activity level. Bruising with pallor, fatigue, or enlarged lymph nodes.
1-3 years
Normal: Toddlers bruise frequently on shins, forehead, and knees from their many falls. Multiple shin bruises are extremely common. Colors change from purple/blue to green/yellow over 1-2 weeks as they heal.
Worry if: Bruising in unusual locations (ears, neck, genitals, trunk). Bruises with shape of objects. Easy or excessive bruising beyond what is expected for activity. Bruising with nosebleeds, bleeding gums, or blood in stool/urine. Large bruises from minor trauma.
Home Care
- Apply a cold compress or ice wrapped in cloth for 10-15 minutes to reduce swelling after injury
- Elevate bruised limbs if possible
- Give age-appropriate pain relief (acetaminophen) if painful — avoid ibuprofen initially as it may increase bleeding
- Gentle pressure for a few minutes after a bump may limit bruise size
- Track bruises with photos and dates if they seem frequent or concerning
- Ensure baby received vitamin K injection at birth (prevents bleeding disease of newborn)
- Remember the rule: "those who don't cruise rarely bruise" — seek evaluation for any bruising in pre-mobile infants
- Normal bruise healing progression: red/purple (day 1-2), blue/dark purple (day 3-5), green (day 5-7), yellow/brown (day 7-14), fading (day 14+)

Bottom line
Most cases of bruising in babies are not emergencies. However, seek immediate care if any bruising in a non-mobile infant (cannot yet pull to stand).
Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.
