In the first 24 hours after birth, a healthy newborn is usually dried and placed skin-to-skin with a parent, offered a first feed, and passes a first dark, sticky stool (meconium) and a first pee. Staff check weight, temperature, and breathing; routine care such as vitamin K, an eye ointment, a hepatitis B vaccine, and newborn screening may be offered — each a choice you make with your provider. Expect a very sleepy baby and an unusual but normal appearance.
This guide covers what is usual in your newborn's first day and the short list of signs that mean call for help, routing every real decision to you and your provider.
Skin-to-skin and the first feed
Soon after birth, a healthy baby is dried and placed bare against a parent's chest. This skin-to-skin contact (kangaroo care) helps steady your newborn's temperature, heart rate, and breathing, and supports early feeding and bonding. Most babies show interest in feeding within the first hour or two. Whether you breastfeed, formula-feed, or combine both is your decision to make with your provider — there is no single right choice. Newborns feed often, roughly 8 to 12 times in 24 hours.
The first diapers: meconium and the first pee
Your newborn's first stool is meconium — a dark, sticky, tar-like substance that built up before birth. Most babies pass it within the first 24 hours, and a first wet diaper usually appears the same day, turning lighter yellow or green over the next few days. Even one wet and one dirty diaper is reassuring, climbing to about six or more wet diapers a day after the first week. If your baby has not had any wet or dirty diaper by 24 hours of age, let your provider know.
Routine newborn procedures and checks
In the first day, your care team will offer several routine measures — each a choice you make with your provider, who will explain the reasons:
- Vitamin K: an injection to help your baby's blood clot and prevent a rare bleeding problem.
- Eye ointment: an antibiotic ointment to help prevent certain eye infections.
- Hepatitis B vaccine: a first dose, commonly offered soon after birth.
- Weight, length, and head measurements, plus regular temperature, heart-rate, and breathing checks.
- Newborn screening: a hearing screen and a blood-spot (heel-prick) test for rare but treatable conditions.
Which you accept, and when, is up to you and your provider.
How your newborn looks — and why it is usually normal
A newborn's first-day appearance surprises many parents but is usually completely normal:
- A cone-shaped or moulded head from birth, which rounds out over days to weeks.
- Puffy eyes and face, and sometimes swollen genitals or breasts, from fluids and hormones.
- Vernix, a white, waxy coating, and later some dry, peeling skin.
- Blotchy or changing colour, and bluish hands and feet, which can be normal early on.
What is not normal: a blue tint to the lips, tongue, or face, or yellowing of the skin or eyes in the first 24 hours — both are warning signs (see below).
Keeping your newborn warm
Newborns lose heat quickly, so skin-to-skin, a hat, and light layers help keep their temperature stable, and the room should be comfortably warm rather than hot. Avoid overheating, a risk factor for SIDS: your baby should feel warm, not sweaty. Whenever your newborn is put down to sleep, place them on their back on a firm, flat surface with nothing loose around them, and room-share rather than bed-share. Tell your care team if your baby feels unusually cold and will not warm up.
Sleepiness and feeding cues on the first day
Many newborns are very sleepy in the first 24 hours, but a sleepy baby still needs to feed regularly. Watch for early feeding cues — stirring, rooting, mouthing, or hands to the mouth — and offer a feed then, rather than waiting for crying. If your baby sleeps longer than about 3 to 4 hours between feeds, it is usually recommended to wake them to feed until feeding and weight gain are established. You cannot spoil a newborn by responding to them.
The first bath and the cord stump
The first bath is often delayed — commonly several hours or up to a day or more — which helps protect your baby's skin and temperature and preserves the vernix. The umbilical cord stump is clamped at birth and will dry, darken, and fall off on its own over one to three weeks. Keep it clean and dry, let air reach it, and fold the diaper below it. Mention any spreading redness, pus, foul smell, or bleeding to your provider.
When to call for help in the first 24 hours
Most of the first day is calm. Trust your instincts — when in doubt, call.
Get emergency help immediately (call your local emergency number or hospital staff) for:
- Trouble breathing — grunting, flaring nostrils, the chest pulling in, or pauses in breathing longer than about 10 seconds.
- A blue or grey tint to the lips, tongue, or face.
- A baby who is limp, floppy, or very hard to wake, or who has a seizure.
- Green (bilious) vomiting — vomit that is green can signal a bowel blockage and needs emergency care now.
Call your provider the same day for:
- A rectal temperature of 100.4°F (38°C) or higher — the most accurate method at this age. In a baby under 3 months, any fever is urgent, even if your baby seems well.
- A low temperature (below about 97°F / 36.1°C) that will not come up with an added layer.
- Jaundice — yellowing of the skin or the whites of the eyes — in the first 24 hours, which is always a red flag (mild yellowing that appears after day 2–3 in a well baby is common and usually harmless).
- A baby who will not feed, feeds very poorly, or is too sleepy to feed.
- No wet or dirty diaper by about 24 hours of age.
- Repeated, forceful, or projectile vomiting, or vomit that contains blood.
Noisy but normal, and usually not a cause for alarm on their own: sneezing, hiccups, grunting, brief irregular breathing with short pauses in a pink baby, occasional trembling of the chin or hands, and small easy spit-ups. This never overrides your instincts — if something feels wrong, call.

Frequently asked questions
What happens in the first 24 hours after a baby is born?
A healthy newborn is placed skin-to-skin, offered a first feed, and passes a first meconium stool and a first pee. Staff check weight, temperature, and breathing, and may offer routine care such as vitamin K, an eye ointment, a hepatitis B vaccine, and newborn screening — each a choice you make with your provider. Expect a sleepy baby.
What is meconium and when should my newborn first poop and pee?
Meconium is your newborn's first stool — dark greenish-black, sticky, and tar-like. Most babies pass it within the first 24 hours, and a first wet diaper usually comes the same day. If there is no wet or dirty diaper by 24 hours, tell your provider.
What newborn procedures are done in the first day?
Common first-day care includes vitamin K, an eye ointment, a first hepatitis B vaccine, weight and length measurements, a hearing screen, and a blood-spot screening. These are routine offerings, not decisions we rank — your provider will explain each.
Why does my newborn look puffy, cone-headed, or blotchy?
Usually it is normal: a moulded, cone-shaped head, puffy eyes, a white waxy vernix, peeling skin, and blotchy colour that shifts as your baby warms. Blue hands and feet can be normal, but blue lips, tongue, or face are not — seek help right away.
When should I call the doctor in my newborn's first day?
Get emergency help for trouble breathing, pauses in breathing longer than about 10 seconds, or blue lips, tongue, or face. Call the same day for a rectal temperature of 100.4°F (38°C) or higher — in a baby under 3 months any fever is urgent — a baby too sleepy to feed, jaundice in the first 24 hours, or no wet or dirty diaper by 24 hours.
