If your baby has been diagnosed with or you suspect low apgar score concerns, here is what the evidence says.
The short answer
The Apgar score is a quick assessment done at 1 and 5 minutes after birth, rating your baby's heart rate, breathing, muscle tone, reflexes, and color on a scale of 0-10. A score below 7 at 1 minute is common and often improves by 5 minutes. A low 1-minute score alone does not predict long-term problems. The 5-minute score is more important for long-term outlook.
Key takeaways
- The Apgar score is a quick assessment done at 1 and 5 minutes after birth, rating your baby's heart rate, breathing, muscle tone, reflexes, and color on a scale of 0-10. A score below 7 at 1 minute is common and often improves by 5 minutes. A low 1-minute score alone does not predict long-term problems. The 5-minute score is more important for long-term outlook.
- Usually normal when: A 1-minute Apgar of 5-6 that improves to 7 or above by 5 minutes
- Call your doctor if: These concerns are managed at the time of birth by the medical team; after discharge, any breathing difficulties, seizures, or extreme lethargy require emergency evaluation
- Varies by age — see the age-by-age breakdown below
“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.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to AAP, NIH guidelines, the Apgar score is a quick assessment done at 1 and 5 minutes after birth, rating your baby's heart rate, breathing, muscle tone, reflexes, and color on a scale of 0-10. A score below 7 at 1 minute is common and often improves by 5 minutes. A low 1-minute score alone does not predict long-term problems. The 5-minute score is more important for long-term outlook. At 0-1 month, the Apgar score was designed to quickly assess a newborn's condition at birth and guide resuscitation decisions, not to predict long-term outcomes. A score of 7-10 is considered normal, 4-6 may indicate some difficulty adjusting, and 0-3 suggests the baby needs immediate medical intervention. Many babies with low 1-minute Apgar scores improve dramatically by the 5-minute assessment. Factors affecting Apgar scores include prematurity, difficult delivery, maternal medications, and congenital conditions. If your baby had a low Apgar score but subsequent examinations are normal, the prognosis is typically excellent. It is generally considered normal when a 1-minute Apgar of 5-6 that improves to 7 or above by 5 minutes. However, you should contact your pediatrician promptly if these concerns are managed at the time of birth by the medical team; after discharge, any breathing difficulties, seizures, or extreme lethargy require emergency evaluation.
Normal vs. Concerning
By Age
What to expect by age
0-1 month
The Apgar score was designed to quickly assess a newborn's condition at birth and guide resuscitation decisions, not to predict long-term outcomes. A score of 7-10 is considered normal, 4-6 may indicate some difficulty adjusting, and 0-3 suggests the baby needs immediate medical intervention. Many babies with low 1-minute Apgar scores improve dramatically by the 5-minute assessment. Factors affecting Apgar scores include prematurity, difficult delivery, maternal medications, and congenital conditions. If your baby had a low Apgar score but subsequent examinations are normal, the prognosis is typically excellent.
1-3 months
If your baby had a low Apgar score at birth but recovered quickly and subsequent evaluations have been normal, there is generally no reason for ongoing concern. Your pediatrician will monitor development at routine well-child visits. Babies who had persistently low Apgar scores (still low at 5 or 10 minutes) may receive more detailed neurological follow-up.
3-6 months
Developmental milestones continue to be monitored. Most babies with low initial Apgar scores who recovered quickly develop normally. If there were concerns about prolonged oxygen deprivation, your pediatrician may be watching more closely for early signs of developmental delay.
6-12 months
Continued monitoring of milestones. Research shows that a low 1-minute Apgar score alone is a poor predictor of long-term outcomes. The 5-minute score, the need for prolonged resuscitation, and subsequent neurological exams are more meaningful predictors.
What to Tell Your Pediatrician
- Describe when you first noticed low apgar score concerns and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if you have questions about what your baby's Apgar scores mean for their long-term health.
- Mention if you are anxious about a low score and want reassurance.
- 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
- A 1-minute Apgar of 5-6 that improves to 7 or above by 5 minutes
- Your baby responded well to initial stimulation and is now feeding and behaving normally
- All subsequent physical and neurological exams have been normal
- Your pediatrician has no ongoing concerns about your baby's development
- You have questions about what your baby's Apgar scores mean for their long-term health
- You are anxious about a low score and want reassurance
- Your baby had an Apgar below 7 at 5 minutes and you want to understand the follow-up plan
- These concerns are managed at the time of birth by the medical team; after discharge, any breathing difficulties, seizures, or extreme lethargy require emergency evaluation
- You notice developmental delays or unusual neurological symptoms in the weeks and months following a difficult birth
What You Can Do at Home
- Keep track of when you notice low apgar score concerns — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that a 1-minute Apgar of 5-6 that improves to 7 or above by 5 minutes — this is generally within the range of normal.
- At 0-1 month, 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 these concerns are managed at the time of birth by the medical team; after discharge, any breathing difficulties, seizures, or extreme lethargy require emergency evaluation.

Baby Not Crying After Delivery
While a first cry is expected and helps expand the lungs for breathing, not all babies cry immediately at birth, and a brief delay is not always cause for alarm. Some babies breathe and transition normally without a dramatic cry. However, if a baby does not cry or breathe within the first minute, medical intervention including stimulation and resuscitation may be needed.
Meconium in Amniotic Fluid
Meconium-stained amniotic fluid (green or brown fluid) occurs in about 10-15% of deliveries, usually at term or post-term. While many babies born through meconium-stained fluid are perfectly healthy, there is a small risk of meconium aspiration syndrome if the baby breathes in the meconium. The medical team monitors for this and provides appropriate care.

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.
