Common Baby Concerns
Our concern guides cover over 2,500 common baby health questions with age-specific information, action tiers (normal, mention at next visit, call now), and source citations from the AAP, CDC, and WHO.
2705+ evidence-based guides for the questions parents search at 2am. Each tells you what's normal, what to watch, and when to call your doctor.
Polycythemia in Newborns (Too Many Red Blood Cells)
Polycythemia occurs when a newborn has too many red blood cells, making the blood thicker than normal. It can cause a ruddy or deep red skin color and, in significant cases, can affect blood flow to organs. Risk factors include delayed cord clamping, maternal diabetes, and being small or large for gestational age. Most cases are mild and resolve without treatment.
Baby Prefers One Position (Positional Preference)
Many newborns develop a preference for turning their head to one side, which is common and often resolves with simple repositioning strategies. However, a persistent preference may indicate torticollis (tightness in neck muscles), which responds well to stretching exercises and physical therapy when addressed early.
Forceful (Projectile) Vomiting in Newborns
Occasional forceful spit-up can happen in newborns. However, true projectile vomiting (stomach contents shooting forcefully, sometimes across the room) that worsens over days to weeks should be evaluated promptly. In babies 2-8 weeks old, progressive projectile vomiting is a classic sign of pyloric stenosis, a treatable condition requiring surgery.
Prolonged Jaundice (Lasting Over 2 Weeks)
Jaundice lasting longer than 2 weeks in a full-term baby or 3 weeks in a premature baby is considered prolonged and should be evaluated. While the most common cause is breast milk jaundice (harmless), prolonged jaundice can occasionally indicate liver or thyroid problems that need prompt treatment. A simple blood test can help determine the cause.
Transient Neonatal Pustular Melanosis
Transient neonatal pustular melanosis is a harmless skin condition present at birth, appearing as small pustules that rupture easily, leaving dark brown spots (hyperpigmented macules) surrounded by a fine collarette of scale. It is more common in darker-skinned babies, is not an infection, and requires no treatment. The dark spots fade over weeks to months.
Ideal Room Temperature for Baby
The ideal room temperature for a sleeping baby is between 68-72 degrees F (20-22 degrees C). A room that is too warm increases the risk of SIDS. Dress your baby in one layer more than you would wear comfortably, and check their chest or back of neck to assess temperature rather than hands or feet.
Weak Rooting Reflex in Newborns
A weak rooting reflex (where baby turns toward a touch on the cheek to find the breast or bottle) can sometimes contribute to feeding difficulties in newborns. It may be caused by prematurity, sleepiness, recent feeding, illness, or neurological factors. Most babies develop a stronger rooting reflex with time and feeding practice, but persistent weakness should be evaluated.
Safe Sleep Position for Newborns
The safest sleep position for babies is on their back, on a firm flat surface, for every sleep. This recommendation from the AAP significantly reduces the risk of SIDS and sleep-related deaths. Always place your baby on their back until they can roll both ways independently.
Wound From Fetal Scalp Electrode Monitoring
A small wound or mark on your baby's scalp from a fetal scalp electrode (used for internal heart rate monitoring during labor) is common and heals quickly. The wound is typically small, like a tiny scratch or prick, and usually heals within 1-2 weeks with simple care. Keep the area clean and dry.
Baby Scratching Own Face
Newborns commonly scratch their own faces because their movements are uncoordinated and their nails are sharp. This is normal and not a sign of distress. Regular nail trimming is the best prevention. Mittens can be used temporarily but should not be used long-term as babies need to explore with their hands.
Abnormal Newborn Screening Results
An abnormal or positive newborn screening result means that further testing is needed, not that your baby definitely has a condition. Most positive screens turn out to be false positives after confirmatory testing. Newborn screening tests are intentionally sensitive to avoid missing any affected babies, so follow-up testing is essential to determine whether the result is a true positive.
Newborn Screening - Expanded Conditions and What Parents Should Know
Newborn screening is one of the most important public health programs, testing babies for over 35 serious but treatable conditions within the first 24-48 hours of life using a few drops of blood from the heel. The Recommended Uniform Screening Panel (RUSP) has expanded significantly, now including conditions like spinal muscular atrophy (SMA), X-linked adrenoleukodystrophy, and Pompe disease. Early detection through newborn screening can mean the difference between a normal life and severe disability or death for affected babies. Approximately 1 in 300 newborns has a detectable condition.
Normal Skin Peeling After Birth
Skin peeling in newborns is very normal, especially in the first one to three weeks after birth. Babies who were born past their due date often have more peeling. The peeling happens as the skin adjusts from the watery environment of the womb to the drier outside air. No treatment is needed, and the peeling will resolve on its own.
My Newborn Sleeps Too Much
Newborns normally sleep 14-17 hours per day, and some healthy newborns sleep even more. However, in the first few weeks of life, it is important that your baby wakes to feed at least every 2-3 hours. A newborn who consistently sleeps through feedings and is not gaining weight appropriately may need to be evaluated by your pediatrician.
Noisy Sleeping: Grunting, Snoring, and Squeaking
Newborns are notoriously noisy sleepers. Grunting, squeaking, snorting, cooing, and even brief pauses in breathing are all normal during newborn sleep. These sounds are caused by small nasal passages, immature breathing patterns, and active (REM) sleep. Most noisy sleeping resolves as baby grows.
Baby Falling Asleep During Feeds
Many newborns fall asleep during feeding, especially in the first few weeks. The warmth, comfort, and rhythmic sucking are soothing and naturally induce sleep. This is usually normal if your baby is gaining weight well. Techniques like undressing baby, tickling the feet, or switching breasts can help keep a sleepy feeder awake long enough for a full meal.
Frequent Sneezing in Newborns
Frequent sneezing in newborns is completely normal and is not usually a sign of a cold or illness. Newborns sneeze to clear their tiny nasal passages of mucus, dust, and other particles. It is one of the few ways they can clear their nose since they are obligate nasal breathers. Sneezing is actually a healthy reflex.
Distinguishing Spit-Up From Vomiting in Newborns
Spit-up is a gentle, effortless flow of stomach contents (usually a small amount) that is very common in newborns. Vomiting is a forceful expulsion of stomach contents. Most spit-up is normal and does not bother the baby ("happy spitter"). Vomiting, especially if forceful, persistent, green-colored, or associated with poor weight gain, needs medical evaluation.
Excessive Moro (Startle) Reflex in Newborns
The Moro (startle) reflex is a normal primitive reflex present in all newborns. Some babies seem to have a more active or sensitive startle reflex, which can cause them to wake frequently during sleep. This is a normal variation and typically diminishes by 3-4 months of age. Swaddling can help reduce the impact of the Moro reflex on sleep.
Stork Bites and Angel Kisses (Salmon Patches)
Stork bites (on the back of the neck) and angel kisses (on the forehead, eyelids, or between the eyes) are flat pink or red birthmarks caused by stretched blood vessels under the skin. They are the most common type of birthmark, appearing in up to 80% of newborns, and are completely harmless. Most on the face fade by age 1-2, while those on the neck may persist but are typically hidden by hair.
Straining and Grunting to Poop (Infant Dyschezia)
Straining, grunting, and turning red during bowel movements is very common in newborns and is called infant dyschezia. It occurs because babies are learning to coordinate relaxing the pelvic floor while bearing down with the abdomen. It is NOT constipation as long as the stool is soft. It typically resolves by 3-4 months.
Red Eye From Birth (Subconjunctival Hemorrhage)
A subconjunctival hemorrhage (a bright red patch on the white of the eye) in a newborn is a common and harmless result of pressure during delivery. It is caused by tiny blood vessels breaking in the eye during the birth process. It does not affect your baby's vision, causes no pain, and resolves on its own within 1-3 weeks without treatment.
Sucking Blisters on Lips and Hands
Sucking blisters or calluses are common, harmless skin changes caused by the friction of breastfeeding or bottle-feeding. They appear as a thickened, sometimes whitish or blister-like area on the center of the upper lip. Some babies are even born with sucking blisters on their hands or wrists from sucking in the womb. They resolve on their own and do not need treatment.
Safe Swaddling Practices
Swaddling can soothe newborns by mimicking the snug feeling of the womb, but it must be done safely. The swaddle should be snug around the chest but allow room at the hips for natural movement. Stop swaddling as soon as baby shows any signs of rolling, typically around 2-4 months.
