How Do I Know If My Baby Is in Pain?
The short answer
Babies cannot tell us when they hurt, but they communicate pain through behavioral and physiological signs. Key pain indicators include: a distinctive high-pitched, intense cry that differs from hunger or tired cries; facial grimacing (furrowed brow, squeezed-shut eyes, open mouth); body tension or rigidity; pulling away from touch; changes in feeding and sleeping; and increased heart rate. Healthcare providers use validated pain scales (like FLACC or NIPS) to assess infant pain. As a parent, you know your baby's baseline behavior best and can often sense when something is wrong.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
Newborn pain signs include: high-pitched or intense crying, facial grimacing (brow furrow, eye squeeze, nasolabial furrow), limb withdrawal, trembling, changes in breathing pattern, and difficulty settling. The Neonatal Infant Pain Scale (NIPS) assesses facial expression, cry, breathing, arm and leg position, and arousal. Sucrose solution on a pacifier, skin-to-skin contact, and swaddling are evidence-based comfort measures for procedural pain in this age group.
Pain signs become more recognizable as you know your baby better. A pain cry typically sounds different from hunger, boredom, or tiredness cries - it is often more urgent, higher-pitched, and harder to console. Your baby may guard or protect a painful area (pulling a leg up for abdominal pain, or refusing to use a limb for injury). Track when the pain behavior occurs to help your doctor diagnose the cause.
Babies at this age may show pain by reaching for or touching the painful area (pulling at ears for ear infection, rubbing their head). Changes in sleep patterns, appetite, or activity level can signal pain. Teething pain is common but usually mild - extreme distress warrants evaluation for other causes. Pain relief options include acetaminophen and ibuprofen (after 6 months).
Toddlers may begin to localize and point to pain. Watch for behavioral changes: a normally active child becoming quiet and clingy, refusing to walk (could indicate foot or leg pain), or avoiding certain movements. The FLACC scale (Face, Legs, Activity, Cry, Consolability) is widely used in this age group. Validate your child's pain - saying "I can see that hurts" provides emotional comfort.
Older toddlers may start using words for pain: "ow," "hurts," "boo-boo." They can sometimes point to where it hurts, though they may not always be accurate. Use picture-based pain scales (happy face to sad face) to help them communicate pain intensity. Never dismiss a child's expression of pain. Chronic or recurring pain warrants medical evaluation.
What Should You Do?
When to take action
- Your baby crying more than usual when teething
- Brief, intense crying during medical procedures (vaccines, blood draws) that resolves with comfort
- Mild fussiness after minor bumps during normal play
- Your baby being consolable within a reasonable time after the pain stimulus is removed
- Your baby seems to be in pain but you cannot identify the cause
- Pain is interfering with your baby's feeding, sleeping, or daily activities
- You want guidance on appropriate pain relief options for your baby's age
- Inconsolable crying that lasts more than 2-3 hours with no identifiable cause
- Pain with abdominal distension, bloody stool, or vomiting (could indicate serious abdominal condition)
- Pain with fever, lethargy, or refusal to move a limb (could indicate infection or fracture)

Could My Baby Be in Chronic Pain?
Chronic or recurrent pain in babies is pain that persists for weeks or occurs repeatedly. Unlike acute pain which has obvious causes (injury, illness), chronic pain may have less clear origins and can significantly affect your baby's development, sleep, feeding, and quality of life. Common sources include gastrointestinal conditions (reflux, milk protein intolerance), musculoskeletal issues, neurological conditions, or post-surgical pain. If your baby seems persistently uncomfortable, fussy, or has unexplained behavioral changes lasting more than a few weeks, discuss chronic pain with your pediatrician.
Tips for Giving Medicine to My Baby
Giving medicine to babies and toddlers can be challenging. Use the syringe or dropper provided with the medication for accurate dosing - never use a kitchen spoon. Aim the syringe toward the inside of the cheek (not the back of the throat, which can cause choking). Give small amounts at a time, allowing your baby to swallow between squirts. Medications can sometimes be mixed with a small amount of food or milk to improve taste, but check with your pharmacist first. Always use weight-based dosing, not age-based.
Caring for My Baby After Surgery
After surgery, your baby will spend time in a recovery area where nurses monitor their vital signs as anesthesia wears off. Most babies are groggy, fussy, and may refuse food for several hours. Pain management is a priority - your team will provide appropriate pain medication. Follow all discharge instructions carefully, including wound care, medication schedules, activity restrictions, and warning signs. Most babies recover remarkably fast, often returning to normal behavior within days of even significant procedures.
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.
