Co-sleeping Risks and Safer Alternatives

The AAP recommends room-sharing without bed-sharing for at least the first 6 months. Bed-sharing increases the risk of SIDS and sleep-related deaths. Safer alternatives include a bedside bassinet or crib in the parents' room, which keeps baby close for feeding and comfort while maintaining a separate safe sleep surface.

Skin

Cradle Cap Spreading Beyond the Scalp

Cradle cap (infantile seborrheic dermatitis) can sometimes spread beyond the scalp to the eyebrows, behind the ears, neck folds, and other skin creases. This is still generally harmless and will resolve on its own. When it spreads to other areas, gentle cleansing and moisturizing can help, and your pediatrician may recommend a mild medicated cream if needed.

Physical

Safe Holding Positions for Newborns

There are several safe ways to hold your newborn, all of which involve supporting the head and neck. The cradle hold, football hold, and shoulder hold are all safe and comfortable for baby. Always support the head, keep baby close to your body, and avoid any position that could restrict breathing. You will not hurt your baby by holding them.

Medical

Intermittent Crossed Eyes in Newborns

Intermittent crossing of the eyes in newborns is very common and usually normal in the first 3-4 months of life. Your baby's eye muscles are still developing coordination, and occasional misalignment is expected. Most babies develop consistent eye alignment by 4 months of age. If crossing persists beyond 4 months or is constant, an eye evaluation is recommended.

Physical

Overlapping or Curled Toes in Newborns

Overlapping or curled toes in newborns are very common and usually harmless. They are often caused by the baby's position in the womb and typically straighten out on their own as the child grows and begins walking. The fifth (pinkie) toe overlapping the fourth toe is particularly common and rarely requires treatment.

Sleep

Newborn Day-Night Confusion

Day-night confusion is completely normal in the first few weeks of life. In the womb, your baby was lulled to sleep by your daytime movement and became more active at night. It typically resolves on its own by 6-8 weeks as your baby's circadian rhythm develops. Exposure to natural light during the day and keeping nighttime dim and calm helps speed the adjustment.

Skin

Early Diaper Rash in Newborns

Diaper rash in the first weeks is common and usually caused by prolonged contact with wet or dirty diapers. Frequent diaper changes, gentle cleaning, barrier cream, and air drying time can help. Most mild diaper rashes improve within a few days with these simple measures.

Skin

Dry, Cracked Lips in Newborns

Dry, peeling, or cracked lips in newborns are very common and usually harmless. They can result from the transition to a drier environment outside the womb, frequent sucking during feeding, or mild dehydration. Applying a small amount of breast milk or lanolin to the lips can help. Persistent dryness with other symptoms like decreased wet diapers may indicate dehydration.

Skin

Early Eczema Signs in Newborns

Eczema (atopic dermatitis) can appear in babies as early as 2-3 months of age, presenting as dry, red, rough, and sometimes itchy patches, most commonly on the cheeks, scalp, and outer surfaces of the arms and legs. It affects about 10-20% of children and is manageable with regular moisturizing and, when needed, medicated creams prescribed by your pediatrician.

Skin

Erythema Toxicum (Red Blotchy Rash in Newborns)

Erythema toxicum is a very common, completely harmless rash that appears in up to 50% of full-term newborns, usually within the first 2-5 days of life. It looks like red blotches with small yellow or white bumps and can appear anywhere on the body except the palms and soles. It resolves on its own without any treatment.

Feeding

Newborn Excessive Weight Loss

It is normal for newborns to lose up to 7% of their birth weight in the first few days as they lose excess fluid. Breastfed babies may lose slightly more than formula-fed babies. Weight loss exceeding 10% of birth weight is considered excessive and may indicate feeding difficulties or dehydration. Most babies should regain their birth weight by 10-14 days of age.

Digestive

Forceful (Explosive) Bowel Movements in Newborns

Explosive or forceful bowel movements are very common and usually normal in newborns, especially breastfed babies. The loose, watery nature of breastfed stools combined with immature sphincter control often results in loud, forceful pooping. As long as your baby is gaining weight and comfortable, explosive stools are not a cause for concern.

Medical

Blocked Tear Duct in Newborns

A blocked tear duct (dacryostenosis) is very common in newborns, affecting up to 20% of babies. It causes persistent tearing and sometimes yellowish discharge from one or both eyes. The tear duct, which drains tears from the eye into the nose, is not fully open. Most blocked tear ducts resolve on their own by 12 months. Gentle tear duct massage can help.

Medical

Erythromycin Eye Ointment at Birth

Erythromycin eye ointment is applied to newborns' eyes after birth to prevent ophthalmia neonatorum, a potentially sight-threatening eye infection caused by gonorrhea or chlamydia bacteria that can be transmitted during vaginal delivery. It is required by law in most states. The ointment may temporarily blur your baby's vision and cause mild eye irritation.

Medical

Baby's Eyes Rolling Back During Sleep

It is completely normal for babies' eyes to roll back, flutter, or appear to show the whites of their eyes as they fall asleep or during light sleep. This is a normal part of the transition between sleep stages and active (REM) sleep. It is not a sign of seizures when it occurs only during sleep transitions.

Medical

Newborn Eye Swelling After Birth

Mild eye swelling and puffiness in newborns is very common after birth, especially after vaginal delivery, and typically resolves within a few days. It can also be caused by the prophylactic antibiotic eye ointment given after birth. However, significant swelling with yellow or green discharge, especially after the first few days, may indicate a bacterial infection (ophthalmia neonatorum) that requires prompt treatment.

Medical

Facial Nerve Damage at Birth

Facial nerve palsy in a newborn causes one side of the face to droop or not move as well, especially noticeable when the baby cries. It can result from pressure on the nerve during delivery (from forceps or passage through the birth canal) or, rarely, from developmental causes. Most cases from birth pressure resolve completely within a few weeks to months.

Medical

Rapid Breathing After Feeding in Newborns

A brief increase in breathing rate after feeding is common in newborns and is usually normal. The full stomach pushes up on the diaphragm, and the effort of feeding can temporarily speed up breathing. However, persistent rapid breathing (over 60 breaths per minute) during or after feeds, especially with other symptoms, should be evaluated by your doctor.

Feeding

Recognizing Hunger Cues in Newborns

Newborns show hunger through a series of cues: early cues include smacking lips, turning head (rooting), and bringing hands to mouth; active cues include fussing, squirming, and faster movements; and late cues include crying. Responding to early cues makes feeding easier and more successful. Crying is actually a late hunger sign.

Feeding

Very Frequent Feeding (Every Hour) in Newborns

Feeding every hour can be normal during cluster feeding periods, growth spurts, or in the early days of establishing breastfeeding. However, if your baby is feeding every hour around the clock and not gaining weight well, it may indicate ineffective feeding or low milk supply that needs evaluation. Check that your baby is producing adequate wet and dirty diapers.

Medical

Persistent Fencing Reflex (ATNR) in Infants

The asymmetric tonic neck reflex (ATNR), or fencing reflex, is a normal primitive reflex where turning the head causes the arm and leg on that side to extend while the opposite limbs flex. It is present from birth and should fade by 4-6 months. A persistent ATNR beyond 6 months may indicate a neurological concern and should be evaluated.

Medical

Fever in a Baby Under 3 Months Old

A fever in a baby under 3 months old (temperature of 100.4 degrees F / 38 degrees C or higher taken rectally) is always a medical emergency. Go to the emergency room immediately, regardless of how well your baby appears. Young babies' immune systems cannot fight infections as effectively as older children, and a fever could indicate a serious bacterial infection (urinary tract infection, bacteremia, or meningitis) that needs urgent treatment. Do NOT wait to see if the fever goes down. Do NOT give fever medication and stay home - go to the ER first.

Physical

Preventing Flat Spots on Baby's Head (Plagiocephaly)

Flat spots on a baby's head (positional plagiocephaly) are very common because newborn skulls are soft and malleable. Prevention strategies include regular tummy time when awake, alternating head position during sleep, and minimizing time in car seats and bouncers when not traveling. Most mild flat spots improve on their own as baby grows.

Medical

Pulsing Soft Spot (Fontanelle) in Newborns

A pulsing or throbbing soft spot (fontanelle) on your newborn's head is completely normal. The pulsation you see is the heartbeat transmitted through the blood vessels beneath the thin membrane covering the fontanelle. This is a reassuring sign that your baby's circulatory system is functioning well. The fontanelle should be flat or slightly concave when your baby is calm and upright.
