When you become a parent for the first time, it's natural for feelings of joy to mix with anxiety. Is he breathing too fast? Why is his face a little yellow? What does this cry mean? The biggest anxiety for new parents often stems from the "unknown"—not knowing how to judge their baby's health.
In fact, we can judge a baby's health based on the "vital signs" they display. Additionally, this article will provide parents with guidance on how to monitor their baby's health at home and when to seek emergency medical help.

First: Essential Vital Signs of a Newborn: Breathing, Heart Rate, and Temperature
Monitoring Normal Newborn Breathing
Breathing is the first line of defense for life, and the normal rhythm and sound of breathing are fundamental to judging a baby's health.
✅ Normal Newborn Breathing Rhythm:A newborn's normal breathing rate ranges between 40 and 60 breaths per minute. You may notice the baby's breathing quickens during feeding, slows during quiet sleep, and may have brief "pauses" (usually not exceeding 10 seconds), followed by a deep breath and continuation. These are all normal signs of the body adapting to the environment. For example, a baby's breathing rate is faster immediately after feeding, then returns to normal after a few minutes.
🏠 Home Monitoring Methods:
Gently place your hand on the baby's chest or back and observe the number of times the chest rises and falls in one minute. You can also observe the nostrils (they flare slightly with each inhalation).
During sleep, pay attention to the sound of the baby's breathing: Under normal conditions, the sound is almost inaudible, or there is only a light "puffing" sound. If you hear a "snoring" sound like a blocked nose, first check for blockage due to nasal secretions (you can use saline drops to soften and clean them).
⚠️ Abnormal Warning Signs (Requiring Medical Attention):
Breathing rate persistently >60 breaths/minute or <30 breaths/minute.
Appearance of "retractions" in the neck, between the ribs, or above the breastbone during inhalation.
Nasal flaring (nostrils move strongly with breathing) or breathing accompanied by grunting.
Lips, nails, or face turning purple (cyanosis).
Breathing pauses for more than 10 seconds, especially if repeated (e.g., more than 3 times per hour).
Regularity of Newborn Heartbeat
A baby's heart starts beating tirelessly from its time in the mother's womb, pumping blood throughout the body. Compared to adults, the heart rate is faster.
✅ Normal Newborn Pulse Rhythm:
120-160 beats per minute (bpm). The rate may increase during crying, feeding, or fever, possibly reaching 170-180 bpm, then decrease to about 120 bpm during quiet sleep.
🏠 How to Measure:
Keep the baby calm (can be measured during sleep).
For new parents, you can measure the baby's apical pulse, usually just below or slightly inside the left nipple (an area about the size of a thumbnail).
Count for 60 seconds to calculate the number of beats, which is the beats per minute rate.
⚠️ Abnormal Warning Signs:
If the heart rate persistently exceeds 160 bpm (e.g., 170 bpm even when calm), or falls below 100 bpm, along with pallor, poor general condition, and weak feeding, observe the baby's condition and seek medical help.
Newborn Temperature: Maintaining Warmth
A newborn's temperature is like a small room requiring careful attention; they cannot tolerate extreme cold or heat.
✅ Normal Range (Underarm):
36.5°C ~ 37.5°C. A newborn's ability to regulate temperature is weak and easily changes with environmental temperature. You can hug the baby to feel their warmth—if their back is warm but not sweaty, and their hands and feet are slightly cool (peripheral circulation in newborns is weak, cool hands and feet are normal), it means their temperature is appropriate.
🏠 Home Monitoring Methods:
Use an electronic thermometer under the armpit, ensuring the armpit is dry from sweat before measurement to ensure contact with the skin.
Measurement takes about one minute, preferably done when the baby is calm.
Measure once in the morning and once in the evening, or take additional measurements when the baby is in an abnormal state or feeding less.
⚠️ Abnormal Warning Signs:
Fever: Underarm temperature > 37.5°C. For newborns (less than 28 days old), any fever requires immediate medical attention, as it could be a sign of serious infection.
Low temperature: Underarm temperature < 36.5°C. Check if the baby is underdressed or if the environment is too cold, and try to warm them. If the temperature does not rise, seek medical help.
Second: Daily Monitoring: Skin, Output, and Sleep
A newborn's skin, output, and sleep are easily observable daily indicators. By closely monitoring these daily manifestations, you can detect changes in your baby's health in a timely manner.
Pink Skin Color
✅ Normal Appearance:
A baby's skin should be pink and warm, soft to the touch, without obvious spots or blueness. It may be slightly red at birth or have "vernix caseosa," which is normal.
🔍 Common Variations and How to Handle Them:
Physiological Jaundice (Physiological Jaundice):
Many term babies develop mild yellowing of the skin and whites of the eyes on the second or third day after birth, peaking on the fourth or fifth day, and usually fading naturally within two weeks.
🏠 How to Handle:
Increase feeding to help the baby excrete bilirubin.
⚠️ Be Cautious:
If jaundice appears very early (day of birth), color deepens significantly, persists beyond two weeks, or the baby's condition worsens with poor feeding, it might be pathological jaundice requiring immediate medical consultation.
Cyanosis: If lips, nails, or face persistently turn blue, it could indicate lack of oxygen.
How to Handle:
This is an emergency; seek medical help immediately, do not wait and observe.
Pallor or Mottling:
If the skin appears patchy or noticeably pale, it might be due to poor circulation or cold.
How to Handle:
Pay attention to warmth, observe if the baby is lethargic or feeding poorly, and consult a doctor if necessary.
Judging Newborn Health Through Their Output
By monitoring a baby's output, you can understand if their nutrition is sufficient, and if there is dehydration or digestive issues.
Urine:
✅ Normal:
Should urinate once within 24 hours of birth, then increase frequency by 1-2 times daily, and after the sixth day should wet 6-8 diapers or more per day. Urine color should be light yellow or clear.
⚠️ Abnormal:
If no urination for more than 24 hours, try increasing feeding frequency (e.g., breastfeeding every 1-2 hours). If no improvement, contact a doctor to rule out dehydration or urinary tract issues.
When urine color is dark yellow like "concentrated tea," it's often a sign of low fluid intake. A breastfeeding mother can increase her water intake, while formula-fed babies should have formula prepared with correct dilution (avoid over-concentration), and monitor for improvement within a day or two.
Pink crystals appearing on diapers often worry new parents; these are urate deposits, resulting from low urine output and concentration. These crystals usually disappear after a day or two of increased feeding. Remember to gently wipe the baby's bottom with warm water at each diaper change to reduce skin irritation from the crystals.
Meconium:
Passed within 24-48 hours after birth, dark green and sticky.
Transitional Stool:
After meconium, stool turns yellow-green.
Breastfed Stool:
Golden yellow color, semi-liquid or liquid, contains "milk curds," has a sour smell, and frequent bowel movements (can be 5-10 times per day).
Formula-fed Stool:
Light brown color, semi-solid, more formed, and less frequent.
⚠️ Abnormal Signs:
If stool contains streaks of blood, first check for an anal fissure (often from hard stool and friction), you can use a warm water bath then apply a small amount of baby diaper rash cream. If blood streaks persist or are accompanied by mucus, it might be due to milk protein allergy or intestinal inflammation; take a stool sample for medical review.
Be extremely cautious if stool is white (clay-colored), as it may indicate bile duct obstruction; seek medical attention immediately (bile duct issues need early detection and treatment).
Black, tarry stool appearing outside the meconium period could indicate gastrointestinal bleeding; preserve a stool sample and seek immediate medical attention.
If stool is very watery, "projectile" (forceful like "water gun"), and frequency suddenly increases, it could be viral gastroenteritis or lactose intolerance. In this case, change diapers promptly, clean with warm water then apply diaper rash cream to prevent redness, and pay attention to fluid replacement (give oral rehydration salts as per doctor's instructions) to avoid dehydration.
Achieving Healthy Newborn Sleep
Newborn sleep patterns and quality are important indicators of their physical growth and health.
✅ Normal Newborn Sleep:
Newborns sleep a total of 16-20 hours per day, but their sleep is interrupted by hunger into short periods of 2-4 hours—feeding at 3 AM and 6 AM is normal. Parents can observe that the baby's eyes are bright and feeding is vigorous when awake, and when asleep, breathing is regular, facial expressions relaxed, and sometimes the mouth twitches or makes light sounds (like "dreaming"), all normal physiological signs.
Tip for Baby Sleep Position:
Back sleeping is recommended, the advised position to reduce the risk of Sudden Infant Death Syndrome (SIDS). A thin, firm mattress can be placed under the baby, and avoid using pillows or stuffed toys to prevent blockage of nose and mouth.
⚠️ Abnormal:
- Unusual Lethargy: If the baby sleeps for excessively long periods, is difficult to wake, and feeds weakly, there might be an infection or metabolic issue.
- Persistent Irritability: Difficulty sleeping, frequent waking, inconsolable crying, might be due to colic, uncomfortable environment, or other problems.
- Abnormal Movements During Sleep: If the baby has strong limb convulsions (like stiffening), continuous eye rolling, facial cyanosis, or breathing pauses (over 15 seconds), immediately record the time and duration of the episode, and seek medical attention as soon as possible to rule out neurological issues (e.g., epilepsy, low blood sugar, etc.).
Third: Specialized Indicators: Reflexes, Muscle Tone, and Weight
These indicators are primarily assessed by doctors during routine infant check-ups, but knowing these basics helps you, as a parent, communicate better with the doctor and detect potential issues in a timely manner.
Understanding Newborn Primitive Reflexes
These are the baby's instinctive, innate reflexes; their presence and disappearance indicate normal development of the baby's nervous system.
Common Reflexes:
Rooting reflex, Sucking reflex, Grasp reflex, Moro reflex. New parents will encounter these reflexes almost "daily"!
Monitoring Method:
Parents can observe naturally during daily interaction—during feeding, see if the baby turns to search for the nipple (rooting reflex). During play, touch their palm with a toy and see if they grasp it (grasp reflex). If these reflexes are completely absent after birth (e.g., inability to suck, no grasp), or haven't disappeared by the normal time (e.g., strong Moro reflex persisting after 6 months), it may indicate abnormal nervous system development, requiring immediate medical consultation.
Newborn Muscle Tone: A Symbol of Vitality
Muscle tone reflects the health of the baby's muscles and nervous system, and is an important criterion for judging their vitality and development.
✅ Normal Signs:
A healthy newborn's limbs are in a normal flexed position. When you pull their arms or legs, you will feel clear resistance and elasticity.
⚠️ Abnormal Signs:
- Severe Floppiness: Baby's body feels "boneless," limbs dangle, head doesn't lift, and when an arm is pulled and released, it doesn't return to position but falls heavily.
- Severe Stiffness: Limbs are constantly tense, difficult to extend, arms or legs are hard to bend when dressing, head may tilt back, and body stiffens.
Simple Check Parents Can Do:
When holding the baby, feel if they have normal muscle tone—a healthy baby will "cling" a bit to the adult, rather than being completely floppy or stiff. If you notice anything clearly abnormal, inform the doctor for a professional assessment.
Tracking Newborn Weight
Changes in a newborn's weight are "direct data" reflecting whether nutrition is sufficient. By recording weight, parents can adjust feeding methods in a timely manner.
✅ Physiological Weight Loss (Normal Phenomenon):
Within 2-4 days after birth, the baby will pass dark meconium and urine, plus some fluid evaporates from the skin through respiration, so their weight will naturally decrease. This loss is typically between 5% and 10% of birth weight. For example, if birth weight is 3.3 kg, dropping to about 3.0 kg is normal.
However, if weight loss exceeds 10%, pay attention. It might be due to insufficient feeding or excessive fluid loss (e.g., very dry environment). In this case, consult a doctor to assess whether formula supplementation is needed to help the baby regain weight as soon as possible.
Return to Birth Weight and Growth:
The baby's weight should return to birth weight within 7-14 days after birth. After that, weight increases by an average of 20-30 grams per day, gaining over 600 grams by the end of the first month.
Fourth: A Comprehensive Signal: Crying
Crying is the baby's direct communication method
For a newborn who cannot yet speak, crying is their only language to communicate with the world.
✅ Healthy Crying:
A healthy newborn's cry is usually loud, rhythmic, and strong, with a moderate tone. For example, during a diaper change, the baby might cry a few times expressing dissatisfaction, and once swaddled in a warm blanket, stops crying immediately, without pained expressions. This type of crying is like "expressing emotions," doesn't cause stress for parents, but rather makes them feel the baby's vitality.
Cries of Need:
Hunger (short, low sound), Sleepiness (gentle sound), Discomfort (fussy sound).
⚠️Pathological Crying:
- Shrill Crying: Sound like a "shriek," sharp and very high-pitched, might indicate severe headache or abdominal pain.
- Weak Crying: Weak and faint crying, seemingly without energy, or stopping after a few cries. Might result from infection, dehydration, low blood sugar, etc. In this case, the baby's general condition is poor, unwilling to feed, and response is slow.
- Persistent, Inconsolable Crying: No matter how you hold or feed the baby, crying continues, sound is strong and arrhythmic, possibly indicating pain or illness.
Finally, trust your intuition. You are the person who knows your baby best. If you feel that "something is wrong," even without clear symptoms, it's worth consulting a doctor. Parenting is not a test, doesn't require perfection, it requires your attention.
