Caring for a newborn comes down to a short list of essentials: feeding every few hours, safe sleep, keeping the umbilical cord clean, tracking diaper output, and knowing which warning signs need immediate attention. Most of what your baby needs in the first weeks is warmth, milk, and you. Here’s how to handle each part with confidence.
Feeding Your Newborn
Newborns eat frequently. Breastfed babies typically nurse 8 to 12 times in 24 hours, roughly every 2 to 4 hours. In the very first days, your baby may want to eat as often as every 1 to 3 hours as your milk supply establishes itself. This is normal and helps signal your body to produce more milk.
Formula-fed newborns generally eat slightly less often because formula takes longer to digest, but they still need feeding every 3 to 4 hours in the early weeks. Most formula-fed babies take about 2 to 3 ounces per feeding during the first month, gradually increasing as they grow. Whether you breastfeed or formula-feed, watch your baby rather than the clock. Rooting (turning toward your hand when you touch their cheek), sucking on fists, and fussing are all hunger cues. Crying is a late hunger signal, so try to feed before your baby gets to that point.
The best way to know your baby is eating enough is diaper output. After day five, expect at least 6 wet diapers per day. The number of soiled diapers varies, but consistent wet diapers tell you your baby is well hydrated.
Safe Sleep Setup
Place your baby on their back for every sleep, including naps. Use a firm, flat mattress in a safety-approved crib or bassinet, covered only by a fitted sheet. Nothing else belongs in the sleep space: no blankets, pillows, bumper pads, or stuffed animals. These guidelines, recommended by the American Academy of Pediatrics and supported by the CDC, significantly reduce the risk of suffocation and sudden infant death.
Room-sharing (keeping the crib in your bedroom) is recommended for at least the first six months, but bed-sharing is not the same thing. Your baby needs their own flat surface. If you’re worried about your baby being cold, use a wearable sleep sack instead of a loose blanket.
Umbilical Cord Care
The umbilical cord stump typically falls off within one to two weeks. Until then, keep it dry and exposed to air. Fold the front of your baby’s diaper down so it doesn’t cover the stump. Stick with sponge baths rather than tub baths to keep the area dry.
You don’t need to swab the stump with rubbing alcohol. If you notice clear or blood-tinged fluid around the base, clean it gently with a damp cotton swab. If stool gets on the cord, clean it with a soapy washcloth, pat dry, and leave it open to air.
Watch for signs of infection: thick yellow discharge (pus), redness or red streaking around the base, swelling, warmth to the touch, or a foul smell. On darker skin tones, redness can be harder to see, so feel the area instead. Infected skin often feels noticeably warmer than surrounding skin. If you notice any of these signs, or if your baby develops a fever or becomes unusually sleepy or irritable, contact your pediatrician right away.
Bathing Basics
You don’t need to bathe your newborn every day. Three times a week is plenty until your baby becomes more mobile and starts getting into messier situations. While the cord stump is still attached, give sponge baths: lay your baby on a soft towel, keep them mostly covered for warmth, and wash one area at a time with a warm, damp cloth.
Once the stump falls off, you can transition to shallow tub baths. Aim for water around 100°F (38°C). Test it with the inside of your wrist or elbow, where your skin is sensitive enough to detect if it’s too warm. Never leave your baby unattended in water, even for a moment.
Skin-to-Skin Contact
Holding your baby against your bare chest, sometimes called kangaroo care, does more than feel good. It helps stabilize your baby’s heart rate and lowers the risk of hypothermia by letting your body regulate their temperature. This is especially beneficial for babies born early or at a low birth weight, but full-term babies benefit too. Skin-to-skin contact also supports breastfeeding by keeping your baby calm and close to the breast. Try to do it as often as you can in the early weeks. Partners and other caregivers can do it too.
Diapering and Skin Protection
Expect to change a lot of diapers. Newborns can go through 8 to 12 diapers a day in the first weeks. Change your baby promptly after a bowel movement and check frequently for wet diapers to prevent diaper rash. Clean the area thoroughly with each change, using a damp cloth or unscented wipes, and let the skin air-dry briefly before putting on a fresh diaper. A thin layer of barrier cream or petroleum jelly can help protect the skin if you notice any redness developing.
In the first few days, your baby’s stool will be dark, sticky, and tar-like. This is meconium, and it’s completely normal. Over the first week, stools transition to a lighter color. Breastfed babies typically produce yellow, seedy stools, while formula-fed babies tend to have tan or yellowish-brown stools that are slightly firmer.
The Vitamin K Shot
Shortly after birth, your baby will be offered a vitamin K injection. Newborns are born with very low levels of vitamin K, which is essential for blood clotting. Without the shot, babies are 81 times more likely to develop a serious bleeding condition called vitamin K deficiency bleeding, which can occur anytime in the first six months. One in five babies who develop this condition dies from it, and about half of late-onset cases involve bleeding into the brain. The shot has been standard practice since 1961 and is one of the most important protective measures your baby receives at birth.
Temperature and Fever
A rectal thermometer is the most accurate way to check a newborn’s temperature. If your baby is under 3 months old and has a rectal temperature of 100.4°F (38°C) or higher, skip urgent care and go directly to the nearest emergency department or call your pediatrician immediately. Fever in a newborn is always taken seriously because their immune system is still immature and infections can escalate quickly.
Beyond fever, trust your instincts about your baby’s overall behavior. A baby who is unusually difficult to wake, refuses to feed, has a weak or high-pitched cry, or seems limp or unresponsive needs prompt medical attention regardless of what the thermometer says.
Car Seat Safety
Your baby must ride in a rear-facing car seat from the very first car ride home. Newborns need a sufficiently reclined angle in the car seat to keep their airway open, since their head can fall forward in a more upright position and restrict breathing. Most infant car seats have a level indicator or adjustable base to help you get the angle right. Check your seat’s manual for the correct recline position, and make sure the harness straps are snug at or below your baby’s shoulders. You should not be able to pinch any slack in the strap at the shoulder.
Premature babies are especially vulnerable to breathing issues in car seats. If your baby was born before 37 weeks, the hospital may perform a car seat tolerance test before discharge to make sure your baby can sit safely in the seat without drops in heart rate or breathing pauses.
What the First Weeks Actually Look Like
Newborns sleep 14 to 17 hours a day, but never in long stretches. Expect sleep cycles of 2 to 4 hours broken up by feedings. This is exhausting, and it’s temporary. By 6 to 8 weeks, many babies start consolidating their sleep into slightly longer nighttime stretches.
Your baby may sneeze, hiccup, and make strange noises during sleep. Newborns are noisy sleepers, and occasional sneezing is how they clear their tiny nasal passages. Hiccups are harmless and usually bother parents more than babies. Startle reflexes (sudden arm-flinging movements) are also normal and fade within a few months. Swaddling can help reduce startles during sleep, but always place a swaddled baby on their back and stop swaddling once your baby shows any signs of rolling over.
The first weeks are a period of rapid adjustment for both you and your baby. Most of newborn care is repetitive: feed, burp, change, soothe, sleep, repeat. It’s simple in concept and relentless in practice. Accept help when it’s offered, sleep when your baby sleeps if you can, and know that the intensity of these early weeks does ease up.
