Baby Arching Back and Crying During Feeding
The short answer
A baby who arches their back and cries during feeding is often showing signs of discomfort. The most common cause is gastroesophageal reflux (GER) - stomach acid flowing back into the esophagus causes a burning sensation, and the baby arches to try to relieve it. Other causes include an improper latch (breastfeeding), a bottle nipple with too fast or too slow a flow, ear infection pain worsened by swallowing, oral thrush, or being overstimulated. If this is happening regularly, discuss it with your pediatrician.
By Age
What to expect by age
Arching during feeding is most commonly associated with reflux, which peaks around 4 months and usually improves by 12 months. Babies with reflux may arch their back, pull off the breast or bottle, cry, and refuse to continue feeding. Other signs of reflux include spitting up frequently, wet-sounding burps, and fussiness after feeds. If breastfeeding, check for tongue or lip ties that may cause pain during feeding. If bottle feeding, try a slower nipple flow and paced feeding. Keep your baby upright for 20-30 minutes after feeds. Your pediatrician may recommend positioning changes, thickened feeds, or medication if reflux is severe.
Toddlers who arch and cry during meals are less likely to have reflux (which usually resolves by 12-18 months) and more likely to be experiencing food refusal from a sensory or behavioral standpoint. However, toddlers with ongoing reflux or esophageal irritation may refuse certain textures or temperatures. Some toddlers arch and cry at mealtime due to the desire for independence (wanting to self-feed), disliking the food offered, feeling pressured to eat, or being too tired or overstimulated. If arching specifically occurs during swallowing, rule out dysphagia (swallowing difficulty) with your pediatrician.
What Should You Do?
When to take action
- Occasional fussiness during a feeding when overtired or overstimulated
- Brief arching that resolves with a change in position or brief break
- Pulling away from the breast or bottle to look around (common at 3-4 months when babies become more aware)
- Arching and crying during most feedings
- Your baby is not gaining weight well due to feeding difficulties
- Feeding sessions are consistently stressful and taking a long time
- Your baby seems to be in pain during feeding (not just distracted)
- Your baby is refusing all feeds and showing signs of dehydration
- Arching is accompanied by forceful vomiting, especially if projectile (possible pyloric stenosis in young infants)
- Your baby seems to choke, gag, or have difficulty swallowing during feeds
- Arching is constant (not just during feeding) and very rigid - this may be a neurological sign requiring evaluation

Related Behavior Concerns
Baby Reflux / GERD
Gastroesophageal reflux is very common in babies because the valve at the top of the stomach is still maturing. Most infant reflux is uncomplicated, meaning your baby spits up but is otherwise happy and growing well. True GERD, where reflux causes pain, feeding difficulties, or poor weight gain, affects a smaller number of babies and is very treatable.
Baby Spitting Up Frequently
Spitting up is extremely common in healthy babies and is rarely a sign of anything serious. About half of all babies spit up regularly in the first few months, peaking around 4 months and typically resolving by 12 months. If your baby is gaining weight well, seems comfortable, and is a "happy spitter," the spit-up is usually more of a laundry problem than a medical one.
My Toddler Is Aggressive Toward Pets
Toddlers being rough with pets is extremely common and almost never reflects true aggression or cruelty. Young children lack the motor control to be consistently gentle and do not yet understand that animals feel pain the way they do. With patient, consistent teaching about gentle touch and close supervision, most toddlers learn to interact safely with pets by age 3-4.
My Baby Doesn't Seem Attached to Anyone
By 7-9 months, most babies show clear preferences for their primary caregivers and some wariness of unfamiliar people. If your baby seems equally comfortable with everyone and shows no distress when separated from caregivers, it may simply reflect an easy-going temperament. However, if combined with other social differences, it can occasionally warrant further discussion with your pediatrician.
My Baby Arches Their Back
Back arching is very common in babies and usually a normal way of expressing frustration, discomfort, or just stretching and moving. Most babies arch their backs when upset, tired, or trying to see something. However, persistent arching with crying, especially during feeding, can be a sign of reflux or discomfort that should be discussed with your pediatrician.
Baby Flat Affect - Limited Facial Expressions or Emotions
Babies should show a range of facial expressions from early infancy. A social smile (smiling in response to a face or voice) typically appears by 6-8 weeks. By 3-4 months, most babies are expressive - smiling, laughing, frowning, and showing surprise. A baby who consistently shows limited facial expressions, rarely smiles, and does not seem to react emotionally to their environment should be evaluated. While some babies are naturally more serious or observant, persistent flat affect can be an early sign of developmental differences, sensory issues, or, rarely, medical conditions.
