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.
When Should Our Family See a Genetic Counselor?
Genetic counseling is recommended when a baby is diagnosed with or suspected of having a genetic condition, when genetic test results need interpretation, when there is a family history of genetic disorders, or when parents want to understand recurrence risk for future pregnancies. Genetic counselors are specially trained healthcare professionals who help families understand genetic conditions, test results, and their implications.
When Is Genetic Testing Recommended for a Baby?
Genetic testing may be recommended when a baby has multiple birth defects, developmental delays without clear cause, dysmorphic features, a family history of genetic conditions, abnormal newborn screening results, or when a specific genetic condition is suspected. Types of testing include chromosomal microarray, whole exome sequencing, and targeted gene panels. Results can guide treatment, predict outcomes, and inform family planning.
Gentle and No-Cry Sleep Training Methods
Gentle sleep training methods minimize or avoid extended crying by using gradual approaches with ongoing parental presence. Methods include the chair method, gradual retreat, pick-up-put-down, and fading. These tend to take longer than extinction methods (2-4 weeks vs. 3-7 days) but may feel more comfortable for some families. Research supports their effectiveness.
My Baby's Bowed Legs Are Not Straightening
Physiological bowing (normal bowed legs) should begin straightening after age 18-24 months. If bowing persists beyond age 2, worsens, or is asymmetric (more on one side), it may indicate Blount disease, rickets, or other conditions that benefit from treatment. Most persistent bowing is treatable when caught early.
GERD vs Cow's Milk Protein Allergy
GERD and cow's milk protein allergy (CMPA) share many overlapping symptoms including spitting up, fussiness, and poor feeding, making them difficult to distinguish. Up to 40% of infants referred for GERD symptoms actually have CMPA. A 2 to 4 week trial of eliminating cow's milk protein (maternal elimination for breastfed, hydrolyzed formula for formula-fed) can help determine if CMPA is the cause.
GI Bleeding Causes in Baby
Gastrointestinal bleeding in babies has many possible causes, most of which are benign. The most common cause of rectal bleeding is an anal fissure from constipation. Other causes include cow's milk protein allergy, infectious colitis, Meckel diverticulum, and intussusception. The color and amount of blood, along with associated symptoms, help determine the urgency and cause.
What to Feed Baby After a Stomach Bug
After a stomach bug, resume your baby's normal diet as tolerated rather than restricting to bland foods. Breast milk and formula are ideal for recovery. The old BRAT diet (bananas, rice, applesauce, toast) is no longer specifically recommended because it is too restrictive in nutrition. Offer whatever your baby will eat, in small frequent amounts, focusing on hydration first.
My Baby Needs Glasses - What Should I Know?
Babies can be prescribed glasses as young as a few months old for conditions like significant farsightedness, nearsightedness, astigmatism, or to help correct eye alignment issues. Infant glasses have flexible frames, adjustable straps, and polycarbonate lenses for safety. While it may seem early, correcting vision problems in infancy is crucial for normal brain visual development and can prevent lazy eye (amblyopia).
Is Goat Milk Formula Safe for My Baby?
FDA-approved goat milk-based infant formulas are now available in the United States and can be a safe option for healthy, full-term infants. However, raw or unpasteurized goat milk and homemade goat milk formulas are dangerous for infants and should never be used. Goat milk formula is not appropriate for babies with confirmed cow's milk protein allergy (CMPA), as the proteins are very similar and cross-reactivity occurs in up to 90% of cases.
Granuloma Annulare (Ring-Shaped Skin Bumps) in Baby
Granuloma annulare is a harmless skin condition that causes flesh-colored or slightly pink firm bumps arranged in a ring or arc shape. It is not ringworm and is not contagious. The cause is unknown. It typically resolves on its own within 1 to 2 years without treatment, though it may recur.
My Baby's Grasp Reflex Seems Weak
The palmar grasp reflex is present at birth and is one of the primitive reflexes tested in newborn exams. Babies instinctively grip anything placed in their palm. This reflex typically fades by 3-6 months as voluntary grasping develops. A weak or absent grasp reflex at birth may indicate neurological concerns, while a weak voluntary grasp after 4-5 months may suggest a motor delay that warrants evaluation.
My Baby Grinds Their Teeth
Teeth grinding (bruxism) is surprisingly common in babies and toddlers, affecting up to 30% of young children. Most children grind their teeth as they explore their new teeth or self-soothe, and the vast majority outgrow it completely by age 6 with no lasting damage to their teeth.
My Baby Grinds Teeth While Sleeping
Teeth grinding (bruxism) is surprisingly common in babies and toddlers, affecting up to 30% of children. It often begins when babies first get teeth and may continue through early childhood. While the sound can be unsettling, occasional grinding is usually harmless and most children outgrow it by age 6. It may be related to teething discomfort, jaw development, or simply exploring their new teeth.
Gripe Water Safety Concerns
Gripe water is an over-the-counter supplement, not an FDA-regulated medication, and its safety and effectiveness are not well-established. Ingredients vary by brand and may include sodium bicarbonate, fennel, ginger, or other herbal ingredients. The AAP does not recommend gripe water because it is not regulated, may contain harmful ingredients, and has no proven benefit over placebo.
Signs of Gross Motor Delay in My Baby
Gross motor delays involve a baby or toddler being significantly behind in developing large-body movements such as rolling, sitting, crawling, pulling to stand, and walking. While there is a wide range of normal for when children reach these milestones, consistently missing multiple milestones or being very late on key ones may indicate an underlying condition. Early evaluation and intervention with physical therapy can significantly improve outcomes.
Baby Growing Too Fast - Rapid Weight or Height Gain
Babies come in all sizes, and being on a high growth percentile does not automatically mean something is wrong. What matters more than the percentile itself is the pattern - a baby who has always tracked along the 90th percentile is following their own normal curve. Rapid upward crossing of percentile lines (jumping from the 50th to the 95th) is more noteworthy. Breastfed babies cannot be overfed at the breast. For formula-fed babies, ensure appropriate bottle feeding practices. Most "big babies" simply have big parents and are growing as genetically programmed.
Baby Not Growing Fast Enough - Failure to Thrive
Slow weight gain (falling across percentile lines on the growth chart) can have many causes, ranging from simple (not getting enough calories, growth pattern recalibration) to medical (feeding difficulties, food allergies, malabsorption, or underlying conditions). "Failure to thrive" is a clinical term for weight that falls below the 2nd percentile or drops across two major percentile lines. The most common cause is insufficient caloric intake - the baby is not eating enough, not absorbing enough, or burning too many calories. Early evaluation is important because nutrition affects brain development.
Understanding My Baby's Growth Chart
Growth charts show how your baby's weight, length, and head circumference compare to other children of the same age and sex. A percentile number means your baby is larger than that percentage of children — for example, the 50th percentile means average. What matters most is not the specific percentile but that your baby follows a consistent growth curve over time. Crossing two or more major percentile lines (up or down) may warrant investigation.
My Baby Is Falling Off the Growth Curve
While babies do not need to stay at the exact same percentile, dropping across two or more major percentile lines on the growth chart warrants evaluation. Common causes include inadequate caloric intake, increased energy needs, or malabsorption. Your pediatrician tracks growth at every well visit and will flag concerning changes.
My Baby Is Jumping Growth Percentiles
Some upward crossing of percentile lines can be normal, especially in the first year when babies are establishing their genetic growth trajectory. Breastfed babies born small may rapidly catch up. However, rapidly crossing multiple percentile lines upward, especially for weight without matching length gain, may warrant discussion about feeding practices.
Is My Baby Having a Growth Spurt?
Growth spurts are periods of rapid growth that commonly occur around 2-3 weeks, 6 weeks, 3 months, 6 months, and 9 months of age, though they can happen at any time. During a growth spurt, your baby may seem hungrier than usual, nurse or bottle-feed more frequently (cluster feeding), be fussier or clingier, and sleep differently — either more or less than usual. Growth spurts typically last 2-3 days but can continue up to a week.
My Baby Gulps Air While Feeding
Swallowing some air during feeding is normal for all babies, but excessive air gulping can lead to gas, hiccups, and spit-up. Common causes include fast milk flow, poor latch (if breastfeeding), bottle nipple flow that's too fast or slow, and crying before feeds. Simple adjustments to feeding position, pacing, and equipment can usually help reduce air intake significantly.
Patchy Hair Loss in Baby
Patchy hair loss in babies is usually caused by friction from lying on the back (positional alopecia), a very common and harmless condition. Other causes include alopecia areata, scalp ringworm, or cradle cap. Positional hair loss fills in naturally as the baby spends more time sitting up.
Baby Hair Not Growing - Bald Baby Concerns
Hair growth in babies varies enormously and is primarily genetic. Some babies are born with thick hair and some are nearly bald until age 2-3. Both are completely normal. Many babies lose their newborn hair in the first few months (telogen effluvium) and grow new hair that may be a different color or texture. A bald spot on the back of the head from friction (sleeping position) is very common and resolves once the baby is more mobile. Most "bald babies" grow a full head of hair by age 2-3.
