My Baby Arches and Twists During or After Feeding
The short answer
Sandifer syndrome is a condition where babies have episodes of abnormal head, neck, and back arching movements that are linked to gastroesophageal reflux (GERD). These episodes can look frightening and are often mistaken for seizures, but they are actually a reflex response to acid reflux pain. The condition resolves once the underlying reflux is treated, typically by age 2.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
0-6 months
Sandifer syndrome can begin in the early months as reflux becomes apparent. You may notice your baby suddenly arching their back, twisting their head to one side, and stiffening during or shortly after feeds. Episodes typically last 1-3 minutes and can happen multiple times a day. The movements are your baby's involuntary response to the discomfort of acid in the esophagus.
6-12 months
Episodes may continue or worsen as your baby becomes more active. The key distinguishing features from seizures are that Sandifer episodes are almost always associated with feeding times, never occur during sleep, and your baby remains fully conscious throughout. Your baby may also show other reflux signs like spitting up, fussiness, or feeding refusal.
12-24 months
As reflux typically improves with age and dietary changes, Sandifer syndrome episodes usually decrease and eventually stop. If your toddler continues to have these episodes, your doctor may recommend further evaluation of the reflux or consider whether an alternative diagnosis is needed.
What Should You Do?
When to take action
- Your baby occasionally arches their back when fussy or frustrated — this is a common way babies express discomfort
- Your baby stretches or stiffens briefly during a diaper change or when excited
- Mild spitting up after feeds without associated abnormal posturing
- Your baby has repeated episodes of back arching, head turning, or neck twisting that seem to occur around feeding times
- You are unsure whether the movements you are seeing are seizures or something related to feeding
- Your baby is also showing signs of significant reflux such as frequent vomiting, feeding refusal, or poor weight gain
- Your baby has episodes of stiffening, jerking, or abnormal movements that occur during sleep or are not related to feeding
- Your baby loses consciousness, stops breathing, or changes color during an episode
- The episodes are increasing in frequency or your baby is not feeding or gaining weight adequately

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.
