If your baby has been diagnosed with or you suspect calcaneovalgus foot (foot bent up at birth), here is what the evidence says.
The short answer
Calcaneovalgus foot is a very common, benign positional foot deformity noticed at birth in which the baby's foot bends upward (dorsiflexed) toward the front of the shin. It is caused by the foot being compressed in this position during pregnancy. The key feature is that the foot is flexible and can be gently moved to a normal position. Almost all cases resolve completely on their own within weeks to months with simple stretching exercises. It is important to distinguish this from vertical talus, a rigid deformity that requires treatment.

- Usually normal when: Your newborn's foot bends upward toward the shin but can be gently and easily moved to a normal position (this flexibility confirms calcaneovalgus rather than a rigid deformity)
- Call your doctor if: Your newborn has a rigid foot deformity that cannot be passively corrected, combined with other physical findings such as unusual body tone, multiple joint contractures, or signs of a genetic syndrome, requiring comprehensive evaluation

“Fever itself is not an illness — rather, it is a sign or symptom that the body is fighting an infection. Fever stimulates certain defenses, such as the white blood cells, which attack and destroy invading bacteria.”

What Parents Should Know
According to OrthoInfo, AAP, NIH guidelines, calcaneovalgus foot is a very common, benign positional foot deformity noticed at birth in which the baby's foot bends upward (dorsiflexed) toward the front of the shin. It is caused by the foot being compressed in this position during pregnancy. The key feature is that the foot is flexible and can be gently moved to a normal position. Almost all cases resolve completely on their own within weeks to months with simple stretching exercises. It is important to distinguish this from vertical talus, a rigid deformity that requires treatment. At 0-3 months, calcaneovalgus foot is noticed immediately at birth. The foot appears bent upward so that the top of the foot touches or nearly touches the front of the shin. It may look alarming, but the critical distinction is flexibility: when you gently push the foot downward into a normal position, it moves easily without resistance. Your pediatrician may show you gentle stretching exercises, holding the foot in a corrected (plantarflexed) position for a few seconds, repeated several times during each diaper change. Most cases show significant improvement within the first few weeks of life. It is generally considered normal when your newborn's foot bends upward toward the shin but can be gently and easily moved to a normal position (this flexibility confirms calcaneovalgus rather than a rigid deformity). However, you should contact your pediatrician promptly if your newborn has a rigid foot deformity that cannot be passively corrected, combined with other physical findings such as unusual body tone, multiple joint contractures, or signs of a genetic syndrome, requiring comprehensive evaluation.
Normal vs. Concerning
By Age
What to expect by age
0-3 months
Calcaneovalgus foot is noticed immediately at birth. The foot appears bent upward so that the top of the foot touches or nearly touches the front of the shin. It may look alarming, but the critical distinction is flexibility: when you gently push the foot downward into a normal position, it moves easily without resistance. Your pediatrician may show you gentle stretching exercises, holding the foot in a corrected (plantarflexed) position for a few seconds, repeated several times during each diaper change. Most cases show significant improvement within the first few weeks of life.
3-12 months
By this age, the vast majority of calcaneovalgus feet have resolved completely with normal foot position and full range of motion. If your baby's foot has not improved by 3-6 months, your pediatrician may want to take a closer look to ensure the condition is truly calcaneovalgus and not a more rigid deformity such as vertical talus or posteromedial bowing of the tibia. Rarely, a foot-ankle orthosis or referral to a pediatric orthopedist may be recommended for persistent cases.
1-3 years
It would be unusual for a true calcaneovalgus foot to persist into toddlerhood. By the time your child is walking, the foot should have completely normalized. If a foot deformity persists, your pediatrician should evaluate whether a different diagnosis is present. Children who had calcaneovalgus at birth have no long-term foot or ankle problems and require no activity restrictions.
3-5 years
Children who had calcaneovalgus at birth have normal foot development, arch formation, and gait by this age. No ongoing treatment, monitoring, or restriction is needed. If your child has flat feet or foot pain at this age, it is unrelated to the newborn calcaneovalgus and should be evaluated on its own merits.
What to Tell Your Pediatrician
- Describe when you first noticed calcaneovalgus foot (foot bent up at birth) and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if your baby's foot does not move easily to a normal position when you gently push it down, suggesting the deformity may be rigid rather than positional.
- Mention if the foot has not improved by 3 months despite regular gentle stretching exercises.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Your newborn's foot bends upward toward the shin but can be gently and easily moved to a normal position (this flexibility confirms calcaneovalgus rather than a rigid deformity)
- Both feet have similar range of motion and your baby does not seem bothered when the foot is moved
- The upward bending of the foot is improving with gentle stretching exercises over the first few weeks
- Your baby's foot has returned to normal position by 2-3 months of age with or without stretching
- Your baby's foot does not move easily to a normal position when you gently push it down, suggesting the deformity may be rigid rather than positional
- The foot has not improved by 3 months despite regular gentle stretching exercises
- You notice the sole of the foot has a convex or rounded "rocker bottom" appearance, which may indicate vertical talus rather than calcaneovalgus
- Your newborn has a rigid foot deformity that cannot be passively corrected, combined with other physical findings such as unusual body tone, multiple joint contractures, or signs of a genetic syndrome, requiring comprehensive evaluation
- Your baby's foot or ankle develops sudden swelling, redness, or warmth, which could indicate an infection or other acute condition unrelated to calcaneovalgus
What You Can Do at Home
- Keep track of when you notice calcaneovalgus foot (foot bent up at birth) — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that your newborn's foot bends upward toward the shin but can be gently and easily moved to a normal position (this flexibility confirms calcaneovalgus rather than a rigid deformity) — this is generally within the range of normal.
- At 0-3 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Follow any care instructions from your pediatrician. Keep a written log of symptoms to bring to appointments.
- While monitoring at home, seek immediate care if your newborn has a rigid foot deformity that cannot be passively corrected, combined with other physical findings such as unusual body tone, multiple joint contractures, or signs of a genetic syndrome, requiring comprehensive evaluation.
Related Conditions
Toddler Flat Feet (Pes Planus)
Flat feet in babies and toddlers are completely normal. All babies are born with flat feet because the arch has not yet developed, and a fat pad fills the arch area. The arch gradually forms between ages 3-6, and most children develop normal arches without any treatment or special shoes.
My Baby Was Born with Clubfoot
Clubfoot (talipes equinovarus) is a condition where one or both feet are turned inward and downward at birth. It affects about 1 in 1,000 babies and is very treatable. The Ponseti method, which uses gentle casting and bracing, corrects clubfoot in over 95% of cases without major surgery. Treatment typically starts within the first few weeks of life for best results.

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.
Adrenoleukodystrophy (ALD) in Babies
X-linked adrenoleukodystrophy (X-ALD) is a genetic disorder affecting about 1 in 17,000 newborns, caused by mutations in the ABCD1 gene on the X chromosome. It primarily affects boys and impairs the breakdown of very long-chain fatty acids (VLCFAs), which accumulate and damage the myelin sheath in the brain and the adrenal glands. The most severe form, cerebral ALD, typically affects boys between ages 4-10 with rapid neurological decline. Newborn screening now enables early detection, and hematopoietic stem cell transplant or gene therapy performed before significant brain involvement can be life-saving.
