Quick Answer: Newborn jaundice and small amounts of spit-up are common, but worsening jaundice, jaundice in the first 24 hours, poor feeding, forceful vomiting, or unusual sleepiness need medical attention. Newborns typically feed every 2–3 hours. A rectal temperature of 100.4°F (38°C) or higher is an emergency in babies under three months. Always place newborns on their backs to sleep on a firm, flat surface without pillows, blankets, toys, or other soft objects.
Bringing a newborn home is exciting, but it can also feel overwhelming. Babies cannot tell you what hurts, why they are crying, or whether something they are doing is normal. A change in skin color, feeding, stool, sleep, or breathing can leave new parents wondering, “Should I be worried?”
Many of these concerns are part of normal newborn adjustment. Others need a pediatrician’s attention. Knowing the difference can help parents feel more confident and recognize problems early.
As a board-certified newborn care pediatrician in Sugar Land, I believe new parents should receive clear information about what to expect and when to ask for help.
Here are seven common newborn problems parents should know.
1. Newborn Jaundice
Jaundice causes a baby’s skin or the whites of the eyes to look yellow. It is common during the first days after birth because a newborn’s liver is still developing its ability to remove bilirubin from the blood. Most cases are mild, but some babies develop bilirubin levels that need treatment.
Jaundice often starts on the face and can move toward the chest, abdomen, arms, and legs as bilirubin levels increase.
Parents should contact their pediatrician if:
- The yellow color is becoming stronger
- The baby’s eyes look yellow
- The baby is feeding poorly
- The baby is difficult to wake
- Jaundice appears during the first 24 hours
- The yellow color spreads to the legs
A pediatrician may check bilirubin with a skin measurement or blood test. If treatment is needed, phototherapy can safely lower bilirubin levels. Do not try to treat jaundice by placing your newborn in direct sunlight.
2. Feeding Difficulties
Feeding is one of the biggest concerns for new parents.
Newborns commonly feed every two to three hours, although feeding patterns can vary. Parents should pay attention to whether their baby is waking for feeds, sucking effectively, and producing an appropriate number of wet and dirty diapers.
Some babies have difficulty latching. Others become sleepy during feeds or seem interested in feeding but do not take enough milk.
Call your pediatrician if your baby:
- Has a weak suck
- Repeatedly refuses feeds
- Is difficult to wake for feeding
- Vomits repeatedly
- Has fewer wet diapers than expected
- Is not gaining weight appropriately
Feeding problems are especially important in the first weeks because adequate nutrition supports growth and helps prevent dehydration and other complications.
3. Spitting Up and Reflux
Many newborns spit up after feeding. This happens because the digestive system is still developing. Gastroesophageal reflux can begin during the first weeks of life and often improves as babies mature.
Small amounts of milk coming back up after a feed are usually different from forceful or repeated vomiting.
Parents should speak with a pediatrician if vomiting is persistent, forceful, associated with poor weight gain, or accompanied by feeding difficulty or unusual behavior.
One important point is sleep safety. The American Academy of Pediatrics (AAP) notes that even babies who spit up or have reflux should be placed on their backs to sleep on a firm, flat sleep surface. Raising the crib mattress or using sleep positioners is not recommended.
4. Diaper Rash
Diaper rash is extremely common. A baby’s skin spends much of the day exposed to moisture, urine, and stool, which can cause irritation. At least half of babies experience diaper rash at some point.
Parents can help protect the skin by:
- Changing diapers regularly
- Gently cleaning the area
- Allowing the skin to dry
- Using a protective barrier cream when needed
- Avoiding harsh soaps or products that irritate the skin
Most mild rashes improve with basic skin care. However, call your pediatrician if the rash is severe, painful, spreading, does not improve, or occurs with fever.
5. Umbilical Cord Concerns
The umbilical cord stump can look strange to new parents. It becomes dry and usually falls off within one to three weeks. The most important care is simple: keep it clean and dry.
A few drops of blood around the time the stump separates can be normal.
However, parents should contact their baby’s doctor if they notice:
- Active bleeding
- Foul-smelling discharge
- Yellow discharge
- Redness around the base
- Swelling
- Tenderness when the area is touched
These can be signs of infection and should not be ignored.
You may also notice the belly button pushing outward when your baby cries. This can be an umbilical hernia. Many infant umbilical hernias close naturally as the abdominal muscles become stronger.
6. Excessive Crying and Colic
Newborns cry. Sometimes they cry even after being fed, burped, changed, and held.
Crying can be especially difficult for exhausted new parents. Colic is often used when a healthy baby has repeated periods of intense crying without an obvious cause.
Before assuming that crying is colic, I recommend checking the basics:
- Is the baby hungry?
- Does the baby need a diaper change?
- Is the baby too hot or cold?
- Does the baby need to burp?
- Is the baby overtired?
- Does the baby have a fever or seem unwell?
If the crying sounds unusual, is suddenly much worse, or cannot be comforted, contact your pediatrician. A newborn who is crying inconsolably may sometimes be sick.
And there is another important message for new parents: if you feel overwhelmed, put your baby safely in the crib and take a short break. Ask someone you trust for help. Never shake a baby.
7. Sleep and Breathing Concerns
Newborns sleep a lot, and their breathing can sometimes seem irregular. But parents should know what normal sleep looks like and understand safe sleep practices.
The AAP recommends placing babies on their backs for every sleep on a firm, flat, non-inclined surface. The sleep space should be free of pillows, blankets, stuffed animals, bumpers, and other soft objects.
Breathing requires more immediate attention.
Contact a pediatrician immediately if your newborn has:
- Very fast breathing
- Grunting
- Flaring nostrils
- Skin pulling in between the ribs while breathing
- Persistent blue coloring
- Difficulty feeding because of breathing problems
Persistent blue coloring of the lips or face is particularly concerning and requires immediate medical attention.
When Is a Newborn Fever an Emergency?
This is one of the most important things I want new parents to remember.
For babies younger than three months, a rectal temperature of 100.4°F (38°C) or higher requires immediate medical evaluation. Do not wait to see whether the fever goes away on its own.
Do not give fever medicine to a young newborn unless a healthcare professional specifically tells you to do so.
If your baby is difficult to wake, has trouble breathing, is feeding poorly, has persistent vomiting, appears blue, or seems seriously ill, seek urgent medical attention.
When Should Parents Call a Pediatrician?
Trust your instincts. If your newborn does not seem like themselves, call.
You should contact your pediatrician if your baby:
- Is feeding poorly
- Is unusually sleepy or difficult to wake
- Has worsening jaundice
- Has fewer wet diapers than expected
- Has repeated or forceful vomiting
- Has unusual or inconsolable crying
- Has signs of infection around the umbilical cord
- Has breathing difficulty
- Has a fever of 100.4°F or higher if under three months old
For severe breathing difficulty, persistent blue coloring, unresponsiveness, or another life-threatening emergency, seek emergency medical care immediately.
Newborn Care at Gentle Pediatrics

Final Thoughts
Most newborn problems are manageable, and many are part of normal adjustment after birth. Jaundice, spit-up, diaper rash, crying, feeding changes, and umbilical cord changes are all concerns I commonly discuss with new parents.
The key is knowing when a normal newborn behavior becomes a reason to call.
You do not have to figure everything out alone. Keep your baby’s pediatric appointments, track feeding and diapers, follow safe sleep practices, and contact your pediatrician when something does not seem right.
