My Baby Has Croup
The short answer
Croup is a viral infection that causes a distinctive barking cough and sometimes noisy breathing, especially at night. Most cases are mild and can be managed at home with cool mist and comfort. However, if your baby is struggling to breathe, making high-pitched sounds when inhaling, or can't settle, seek immediate medical care.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
0-6 months
Croup is less common in babies under 6 months, so any barking cough or noisy breathing in a young infant warrants a same-day medical evaluation. Young babies have smaller airways and can develop breathing difficulty more quickly. Your doctor may prescribe steroids or monitor your baby closely.
6-12 months
Croup typically starts with cold symptoms and then develops into a distinctive seal-like barking cough, often worse at night or with crying. Your baby may have stridor (a high-pitched noise when breathing in). Cool mist from a humidifier or steam from a hot shower (with you holding your baby safely outside the shower) can help. Contact your pediatrician for guidance, as babies this age may need steroids.
1-2 years
This is a common age for croup. Most cases improve in 3-5 days. Your toddler's cough may sound worse than it is, especially at night. Keep them calm, use a cool mist humidifier, and offer fluids. Crying can make breathing harder, so comfort is key. If your child is working hard to breathe or has stridor at rest, seek medical care.
2-3 years
Croup is still common in this age group. Your child might say their throat hurts or that it's hard to breathe. Watch for signs of respiratory distress: flaring nostrils, visible ribs or belly moving excessively with breathing, or pale/blue lips. Most cases are mild, but don't hesitate to call your pediatrician if you're worried.
3 years+
Croup becomes less common as children get older. If your older child has barking cough and stridor, it's still likely croup, but your pediatrician may want to rule out other causes. Treatment is the same: comfort, cool mist, and monitoring for breathing difficulty.
What Should You Do?
When to take action
- Your child has a barking cough but is breathing comfortably when calm
- The cough is worse at night but your child can sleep with a humidifier
- Your child is drinking fluids, making wet diapers, and has some energy during the day
- The barking cough improves after a few minutes of cool mist or going outside in cool air
- Your child had a mild cold for a day or two before the barking cough started
- Your child has a barking cough and you want guidance on home care
- Your child seems more tired than usual or is eating less than normal
- The croup symptoms haven't improved after 3-4 days
- Your child has a fever lasting more than 3 days
- Your child is struggling to breathe, with visible chest pulling in or flaring nostrils
- Your child makes a high-pitched noise (stridor) even when calm and at rest
- Your child's lips or skin turn blue or pale
- Your child is drooling, can't swallow, or refuses all fluids
- Your baby is under 3 months with any barking cough or noisy breathing

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.
