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.
Rib Pain From Baby Kicking
Rib pain during pregnancy is common in the third trimester and is caused by the expanding uterus pushing against the rib cage, hormonal loosening of rib joints, and the baby kicking or pressing against the ribs. While uncomfortable, it is usually harmless and resolves after the baby drops lower or after delivery.
Sciatic Nerve Pain in Pregnancy
Sciatica during pregnancy involves pain that radiates along the sciatic nerve, from the lower back through the buttock and down the leg. It affects roughly 1% of pregnant people and is caused by the growing uterus putting pressure on the sciatic nerve, hormonal changes loosening joints, or the baby's position.
Breathing Difficulty in Pregnancy
Shortness of breath affects up to 75% of pregnant people. It is caused by hormonal changes (progesterone increases respiratory drive), increased oxygen demand, and the growing uterus pushing the diaphragm upward. While usually normal, sudden or severe breathlessness should be evaluated promptly.
Skin Darkening, Linea Nigra, and Melasma in Pregnancy
Skin darkening (hyperpigmentation) during pregnancy is very common and affects up to 90% of pregnant people. It is caused by increased melanin production driven by pregnancy hormones. Common changes include the linea nigra (dark line on the belly), melasma (dark patches on the face), and darkening of the areolas, freckles, and moles.
Stretch Marks During Pregnancy
Stretch marks (striae gravidarum) affect up to 90% of pregnant people and occur when the skin stretches rapidly as the belly, breasts, and hips grow. They appear as pink, red, or purple streaks and gradually fade to silver or white after pregnancy. Genetics plays the biggest role in whether you develop them.
Swelling in Feet, Ankles, and Hands During Pregnancy
Mild to moderate swelling (edema) in the feet, ankles, and hands is very common in pregnancy, affecting about 80% of pregnant people. It is caused by increased blood volume and fluid retention, and it is usually harmless. However, sudden or severe swelling, especially in the face and hands, can be a warning sign of preeclampsia.
Thyroid Problems in Pregnancy
Thyroid disorders are the second most common endocrine condition in pregnancy. Both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) can affect pregnancy outcomes if untreated. Proper monitoring and treatment ensure healthy outcomes for both parent and baby. If you have a known thyroid condition, medication adjustments are often needed during pregnancy.
Travel During Pregnancy
Travel during pregnancy is generally safe for most people with uncomplicated pregnancies. The second trimester (14-28 weeks) is often considered the best time to travel, as morning sickness has typically passed and energy levels are higher. Always wear your seatbelt with the lap belt under your belly, take breaks to walk on long trips, and carry a copy of your prenatal records.
UTI During Pregnancy
Urinary tract infections (UTIs) are common during pregnancy, affecting 2-10% of pregnant people. Pregnancy increases UTI risk due to hormonal changes that relax the urinary tract and the growing uterus compressing the ureters. Untreated UTIs during pregnancy can lead to kidney infections and pregnancy complications, so prompt treatment with pregnancy-safe antibiotics is important.
Normal Vaginal Discharge Changes in Pregnancy
Increased vaginal discharge (leukorrhea) is a normal and expected change during pregnancy. It is typically thin, white or clear, and mild-smelling. This increased discharge helps protect the birth canal from infection and maintains a healthy balance of bacteria. Changes in color, odor, or consistency may indicate an infection and should be evaluated.
Varicose Veins in Pregnancy
Varicose veins are swollen, twisted veins that commonly appear in the legs during pregnancy. They affect up to 40% of pregnant people and are caused by increased blood volume, hormonal changes that relax vein walls, and pressure from the growing uterus on pelvic veins. They are usually a cosmetic concern but can cause aching or discomfort.
Vivid or Disturbing Dreams During Pregnancy
Vivid, intense, or disturbing dreams are extremely common during pregnancy. They are caused by hormonal changes, increased REM sleep disruptions from waking frequently at night, and the natural anxieties and excitement of becoming a parent. These dreams do not predict the future and are not a sign that something is wrong.
Pregnancy Weight Gain: Too Much or Too Little
Weight gain during pregnancy varies, but general guidelines recommend 25-35 pounds for normal-weight individuals, 28-40 pounds for underweight, 15-25 pounds for overweight, and 11-20 pounds for obese individuals. These are just guidelines - your provider will help you determine what is healthy for your body. Focus on nutrition quality rather than the number on the scale.
Yeast Infections During Pregnancy
Yeast infections are more common during pregnancy due to higher estrogen levels and changes in vaginal pH that promote Candida overgrowth. They affect about 1 in 4 pregnant people. While uncomfortable, yeast infections do not harm the baby during pregnancy. Topical antifungal treatments are safe and effective during pregnancy.
Premature Adrenarche - Early Body Odor or Pubic Hair in My Child
Premature adrenarche is the early activation of the adrenal glands, producing mild levels of androgens (hormones) that can cause body odor, oily skin, mild acne, and sometimes sparse pubic or underarm hair in children as young as 4 to 8 years old. It is usually a benign variant of normal development and does not represent true puberty. However, it should be evaluated by your pediatrician to rule out other conditions such as congenital adrenal hyperplasia or precocious puberty.
Premature Baby Milestones and Adjusted Age
Premature babies should be assessed using their "adjusted age" (also called corrected age) for developmental milestones, not their actual birth date. Adjusted age is calculated by subtracting the number of weeks of prematurity from their actual age. For example, a baby born 8 weeks early who is now 6 months old has an adjusted age of 4 months. Use adjusted age for milestone expectations until age 2-3 years, when most premature babies catch up with their full-term peers. Most premature babies develop normally, though they may reach milestones on a slightly different timeline.
Feeding Difficulties in Premature Babies at Home
Feeding difficulties are among the most common challenges parents of premature babies face after NICU discharge. Preemies often have immature suck-swallow-breathe coordination, tire easily during feeds, and may take smaller volumes more frequently than full-term babies. These difficulties typically improve as your baby matures, but it is important to work closely with your pediatrician and possibly a feeding therapist to ensure your baby is gaining weight appropriately.
Premature Baby Immune System: Protecting Your Preemie
Premature babies have less mature immune systems than full-term infants because they missed out on maternal antibodies that transfer most actively during the third trimester of pregnancy. This makes them more susceptible to infections, particularly respiratory illnesses like RSV and influenza. Protective measures include limiting visitors, practicing strict hand hygiene, keeping up with vaccinations on the chronological (not adjusted) age schedule, and considering RSV immunization with nirsevimab.
Premature Rupture of Membranes (PROM/PPROM)
Premature rupture of membranes (PROM) occurs when the amniotic sac breaks before labor begins. When this happens before 37 weeks, it is called preterm premature rupture of membranes (PPROM) and requires immediate medical attention. PPROM affects about 3% of pregnancies and is a leading cause of preterm birth.
Premature Thelarche - Breast Development in My Baby or Toddler
Premature thelarche is isolated breast development in girls typically under age 3, without other signs of puberty such as pubic hair, growth acceleration, or vaginal bleeding. It is usually a benign, self-limiting condition caused by transient sensitivity to low levels of estrogen. In most cases, the breast tissue waxes and wanes and eventually resolves on its own without treatment. However, your pediatrician should evaluate it to ensure it is not the beginning of true precocious puberty.
Depression During Pregnancy
Depression during pregnancy (prenatal or antenatal depression) affects approximately 10-20% of pregnant people. It is a real medical condition caused by a combination of hormonal changes, life stressors, and individual risk factors. It is not a character flaw, and it is treatable. Getting help during pregnancy is important for both your health and your baby's well-being.
Anxiety About Prenatal Tests
Anxiety about prenatal tests is extremely common. Many parents feel nervous about what tests might reveal. Remember that most screening tests have a high rate of reassuring results, and even abnormal screenings often turn out to be false positives. You have the right to choose which tests you want and to decline any test. Understanding what each test tells you can help reduce anxiety.
How to Prepare for Your Baby's Doctor Visit
Preparing for your baby's doctor visit helps you get the most out of your limited appointment time. The AAP recommends writing down your questions and concerns in advance, bringing your baby's insurance card and any relevant medical records, and noting recent feeding, sleeping, and developmental milestones. For well-child visits, expect growth measurements, a physical exam, developmental screening, and vaccinations. For sick visits, document symptoms including onset, duration, fever readings, feeding changes, and diaper output. Having a written list ensures you don't forget important questions when you're in the room. The AAP notes that parents who prepare written questions tend to report higher satisfaction with pediatric visits and better recall of medical advice.
How to Prepare Formula Safely
Safe formula preparation involves using clean water, following the manufacturer's mixing instructions exactly, and practicing good hygiene with bottles and equipment. Using too much or too little water can be dangerous for your baby. The CDC recommends using water from a safe source and, for babies under 3 months or those who are immunocompromised, boiling and cooling the water before mixing.
