Baby Bruises: What's Normal & When to Worry | Parenting Hub
Mobile babies bump and bruise. But bruises in a baby who isn't yet cruising or crawling need a medical review — here's why.
Once babies are mobile, small bumps and bruises are part of life. But bruising in a baby who isn't yet rolling, cruising or crawling always needs a medical review — even if there's a simple explanation.
Bruises in mobile vs non-mobile babies
Once babies start rolling, cruising and crawling, shin and forehead bumps are expected. In babies who aren't yet mobile, however, bruising is unusual — and Australian guidelines (RCH Melbourne) recommend any unexplained bruise in a non-mobile baby is reviewed by a doctor the same day. This isn't about blame; it's a routine safety check.
What might cause bruising
Common explanations include accidental knocks during handling, dressing or carrier use, very rare bleeding disorders, or non-accidental injury. A doctor will check the pattern and may do simple blood tests.
Caring for a bruise
A cool compress for 10 minutes can help in the first few hours. Don't use ice directly on a baby's skin. Bruises typically fade through purple, green and yellow over 1–2 weeks.
When to seek help
- Any bruise in a baby who isn't yet rolling/crawling — see GP today
- Multiple bruises, or bruises in unusual spots (ears, neck, back, buttocks)
- Bruise plus tiny pinprick spots that don't fade under pressure (call 000)
- Bruising with bleeding gums or nosebleeds
Common questions
My baby bumped their head on the cot — is that bruise okay?
If you witnessed the bump, your baby fed and behaved normally afterward, and the bruise is small and isolated, mention it at your next nurse visit. Any change in alertness, vomiting or unusual sleepiness needs immediate review.
Why do doctors take unexplained bruising so seriously?
Because pre-mobile babies don't bruise themselves. Doctors are trained to consider all causes — most are innocent, but a thorough check protects your baby.
