My Baby or Toddler Is Limping
The short answer
A limp in a baby or toddler always deserves medical attention, as young children cannot reliably tell you where it hurts. The most common cause in toddlers is a minor injury such as a 'toddler's fracture' (a subtle shin bone crack) or muscle strain. However, limping can also indicate infection in a joint or bone, hip problems, or other conditions that need prompt evaluation.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
6-12 months
Babies at this age are not yet walking independently, but you may notice them favoring one leg during crawling, pulling to stand, or cruising. Asymmetric movement in an infant can indicate hip dysplasia, a fracture (including non-accidental injury that should be considered), infection of a bone or joint (osteomyelitis or septic arthritis), or a neurological condition. Any asymmetry in leg use, reluctance to move a leg, or swelling of a joint in an infant requires same-day pediatric evaluation.
1-2 years
New walkers are prone to 'toddler's fractures,' a subtle spiral fracture of the tibia (shinbone) that occurs from a twisting fall. The child may refuse to bear weight or limp without obvious swelling. These fractures sometimes do not show up on initial X-rays and may need repeat imaging. Transient synovitis (irritable hip), a temporary inflammation of the hip joint often following a viral illness, is another common cause. Septic arthritis (infected joint), though less common, requires urgent treatment and should be ruled out when fever is present.
2-3 years
In addition to injuries, toddlers at this age can develop transient synovitis, growing pains (which typically occur at night and do not cause actual limping), or rarely, conditions like Legg-Calve-Perthes disease (loss of blood supply to the hip bone) or juvenile arthritis. A child who limps for more than a few days, limps with fever, or has progressive worsening of the limp should be evaluated. Your doctor may order X-rays, blood tests, and possibly an ultrasound of the hip.
What Should You Do?
When to take action
- A brief, mild limp after a witnessed minor fall that resolves within 24-48 hours with the child returning to normal activity
- Occasional unsteady gait in a new walker who is still developing coordination (this is not a true limp)
- Mild limping in the morning that resolves quickly after getting up and moving, with no other symptoms
- Your toddler has been limping for more than 2-3 days even without a known injury
- The limp seems to come and go over weeks or is gradually worsening
- Your child avoids using one leg, refuses to crawl on one side, or consistently holds one leg differently than the other
- Your child has a limp with fever, which may indicate a serious joint or bone infection (septic arthritis or osteomyelitis) requiring emergency evaluation - especially if a joint appears red, swollen, or warm, or the child refuses to move the limb at all
- Your child suddenly cannot bear any weight, is in severe pain, has significant swelling of a joint, or the limb appears deformed, as these require immediate medical assessment

My Baby's Head Shape Looks Abnormal
Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.
Achondroplasia (Dwarfism) in Babies
Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
Adenoid Hypertrophy and Breathing
Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.
How to Advocate for Your Child's Needs
You know your child better than anyone, and your observations matter. If you feel something is not right with your child's development or health, you have every right to ask questions, request evaluations, and seek second opinions. Advocating for your child is not being difficult - it is being a good parent.
Air Quality and Baby Health
Babies and young children are more vulnerable to air pollution than adults because they breathe faster, their lungs are still developing, and they spend more time close to the ground where some pollutants concentrate. The EPA recommends keeping babies indoors when the Air Quality Index (AQI) exceeds 100 (orange level). During wildfire smoke events, keep windows closed, use air purifiers with HEPA filters, and monitor your child for coughing, wheezing, or difficulty breathing. Long-term exposure to air pollution can affect lung development.
Altitude Sickness in Babies
Babies and toddlers can experience altitude sickness when traveling above 5,000-8,000 feet (1,500-2,500 meters). Symptoms are harder to recognize in infants because they cannot describe how they feel. Watch for unusual fussiness, poor feeding, disrupted sleep, vomiting, and fast breathing. Gradual ascent is the best prevention. Most pediatricians recommend avoiding sleeping at very high altitudes (above 8,000 feet) with infants when possible, and descending immediately if symptoms appear.
