In the first weeks of life, your newborn needs a small number of things done well: frequent feeding, safe sleep, skin-to-skin contact, and short bursts of supervised tummy time. That’s genuinely most of it. The rest is learning your baby’s cues and taking care of yourself while you do it. Here’s what each of those priorities looks like in practice.
Feeding: Small Stomachs, Frequent Sessions
A newborn’s stomach is surprisingly tiny. On day one, it holds about 5 to 7 milliliters, roughly a teaspoon. By day three it expands to about 22 to 27 milliliters, and by one week it reaches 45 to 60 milliliters (1.5 to 2 ounces), about the size of an apricot. This is why newborns eat so often. Eight to twelve feedings in a 24-hour period is normal, and some cluster even more than that, especially in the evenings.
Whether you’re breastfeeding or using formula, expect your baby to lose some weight in the first few days. Breastfed infants lose an average of about 6.6% of their birth weight before they start gaining again, typically around day three. Anything under 10% is considered within the normal range, though losses approaching that mark may prompt your pediatrician to check in more closely. Most babies regain their birth weight by about two weeks.
The best way to track whether your baby is getting enough milk is by counting diapers. On day one, expect one wet diaper and one dark, tarry stool. By day two, look for two to three wet diapers and one to two stools that start shifting from black to greenish. By day five and beyond, you should see at least six wet diapers and four or more soft, yellow, seedy stools every 24 hours. If those numbers drop off, it can signal that your baby isn’t taking in enough.
Skin-to-Skin Contact
Holding your baby against your bare chest, sometimes called kangaroo care, is one of the most beneficial things you can do in the early weeks. When a newborn is placed skin-to-skin, the parent’s breast temperature actually rises to help warm the baby, which shows up as warmer foot temperatures in the infant. That warming effect is a sign the baby’s stress response from birth is calming down. Babies held this way also cry less and stay warmer without needing extra blankets or devices.
You don’t need a schedule for this. Any time you’re sitting or reclining and can safely hold your baby against your chest counts. It works for both parents and can be done while feeding, resting, or just sitting quietly. Beyond temperature regulation and stress reduction, it helps your baby get familiar with your heartbeat, voice, and smell, all of which support early bonding.
Tummy Time Starting Day Two
Most babies can begin tummy time a day or two after birth. In the beginning, aim for two or three short sessions per day, each lasting about three to five minutes. That may not sound like much, but for a newborn with almost no neck strength, it’s a real workout. You can place your baby on your chest while you recline if a flat surface feels too intense at first.
Tummy time builds the neck, shoulder, and core muscles your baby will eventually need for rolling, sitting, and crawling. As your baby gets older and stronger over the coming weeks, you can gradually extend sessions and add more throughout the day. If your baby fusses, that’s normal. Try shorter bursts, change the surface, or get down on the floor face-to-face so they have something interesting to look at.
What Your Baby Can Actually See and Hear
Newborns can focus on objects about 8 to 10 inches from their face, which happens to be the distance between your face and theirs during feeding. Beyond that range, the world is mostly a blur. High-contrast patterns (black and white stripes, bold shapes) are easier for them to see than soft pastels. You don’t need special toys for this. Your face is the most interesting thing in their world right now.
Talking to your baby, narrating what you’re doing, singing, reading aloud: all of it matters even though they can’t understand words yet. Hearing language from a real person builds the neural pathways for speech and helps your baby learn the rhythms of conversation. You’ll notice your newborn turning toward your voice or going still when you speak. Those are early signs of engagement, not coincidence.
Reflexes You’ll Notice
Your baby was born with a set of automatic reflexes that serve specific survival purposes. The rooting reflex causes them to turn their mouth toward anything that brushes their cheek, helping them find the breast or bottle. The sucking reflex kicks in when something touches the roof of their mouth. The grasp reflex makes their fingers curl tightly around anything pressed into their palm. And the Moro (startle) reflex causes them to fling their arms out and cry when they feel a sudden loss of support, like when you lower them into a bassinet too quickly.
These reflexes are completely normal. They’re controlled by the brainstem rather than conscious thought, and most fade by around six months as your baby gains voluntary control of their movements. If you notice the startle reflex disrupting sleep, a snug swaddle (with hips loose) can help dampen it.
Safe Sleep Basics
Every sleep, whether a nap or nighttime, should follow the same rules. Place your baby on their back on a firm, flat mattress in a safety-approved crib or bassinet. Nothing else goes in the sleep space: no blankets, pillows, bumper pads, or stuffed animals. Keep the crib in your room for at least the first six months.
Overheating is a risk factor for sudden infant death, so dress your baby in one layer more than what you’d find comfortable, and skip hats indoors. If your baby’s chest feels hot to the touch or they’re sweating, they’re too warm. Offering a pacifier at sleep times is associated with reduced risk as well. If you’re breastfeeding, you can wait until feeding is well established (usually a few weeks) before introducing one.
Cord Care and Bathing
The current recommendation for the umbilical cord stump is simple: keep it clean and dry. No alcohol swabs, no antiseptic ointments. Just fold the diaper below the stump so it stays exposed to air, and let it fall off on its own. With dry care, the stump separates in about seven days on average, roughly a day faster than with alcohol cleaning. Neither approach carries a meaningful infection risk in a typical home setting.
Until the stump falls off, stick to sponge baths rather than submerging your baby in water. After it separates and the area heals, you can move to a shallow tub bath. Newborns don’t need daily baths. Two or three times a week is plenty, since frequent bathing can dry out their skin.
Tracking Diapers and Weight
In the first week, diaper output is your best window into whether feeding is going well. Here’s what to expect from a breastfed baby:
- Day 1: 1 wet diaper, 1 black tarry stool
- Day 2: 2 to 3 wet diapers, 1 to 2 greenish-black stools
- Days 3 to 4: 3 to 4 wet diapers, at least 3 green-to-yellow soft stools
- Day 5 onward: 6 or more wet diapers, at least 4 yellow seedy stools
Formula-fed babies tend to have slightly fewer, firmer stools, but the wet diaper count is similar. A sudden drop in wet diapers, dark or concentrated urine, or persistent weight loss beyond 10% of birth weight are signs your baby may not be getting enough to eat.
Warning Signs That Need Immediate Attention
Newborns under two months old with a rectal temperature of 100.4°F (38°C) or higher need emergency evaluation. This is non-negotiable, even if the baby seems otherwise fine. A fever at this age can indicate a serious infection that progresses quickly.
Other signs to act on promptly: fewer wet diapers than expected for their age in days, a yellowish tint to the skin or eyes that worsens after day three, difficulty waking for feeds, a weak or high-pitched cry that sounds different from their usual fussing, or any blue or gray coloring around the lips or face. You’ll develop a sense of your baby’s baseline behavior quickly, and when something feels off, that instinct is worth following.
What You Don’t Need to Worry About
Newborns sneeze frequently because it’s the only way they can clear their nasal passages. They hiccup after nearly every feeding. Their breathing is irregular, sometimes fast and sometimes pausing for a few seconds, which is normal as long as they aren’t turning blue or gasping. Their hands and feet may look slightly bluish for the first day or two as circulation matures. Peeling skin, especially on the hands and feet, is common in the first week and doesn’t need lotion.
You also don’t need to entertain your newborn. At this stage, feeding them, holding them, talking to them, and giving them a few minutes of tummy time each day is providing exactly the stimulation their developing brain needs. The 8-to-10-inch focal distance of their vision means your face during a feeding is perfectly positioned, and that’s genuinely the most important thing they’re looking at right now.
