The first month with a newborn is a strange exam: everything looks alarming, nobody gives you the syllabus, and the baby cannot tell you the answers. Most of what frightens new parents is completely normal. A few things are not, and those few matter enormously. Here is how to tell them apart.

Feeding

Normal: Feeding 8 to 12 times in 24 hours, including at night - a newborn's stomach is tiny and empties fast. Cluster feeding in the evenings (back-to-back feeds for hours) is exhausting but typical. After the first few days, expect at least 6 wet nappies a day; that count is your best home proof that milk is going in. Regular swallowing during feeds, and a baby who comes off the breast or bottle looking milk-drunk, are good signs.

Not normal: A baby too sleepy or too weak to feed, feeds that suddenly take much longer with the baby working hard and sweating, repeated vomiting of most feeds (spitting up small amounts is normal; forceful vomiting is not), or fewer wet nappies day after day. Poor feeding in a newborn is never a "wait and see" - read the full guide here.

Weight

Normal: Losing up to about a tenth of birth weight in the first few days, then regaining it by around two weeks. Grandparents will panic about the initial drop. It is expected, and it is why the early weight checks exist.

Not normal: Weight still below birth weight after two weeks, or poor weight gain alongside poor feeding - this needs your paediatrician's eyes on the baby, and usually a feeding review.

Sleep

Normal: Sixteen hours a day or so, chopped into 2-4 hour pieces around the clock, with days and nights thoroughly confused. Grunting, squeaking, twitching and brief pauses in breathing followed by a few fast breaths are all standard newborn noises. Newborns are loud sleepers; you will not sleep through the noise even when the baby does.

Not normal: Breathing pauses longer than about 20 seconds, a blue tinge around the lips, persistent grunting with the chest pulling in, or flaring nostrils with every breath. Those are breathing-emergency signs - act, don't watch.

One rule that is not negotiable: baby sleeps on their back, on a firm flat surface, in your room, with nothing soft in the cot - no pillows, no loose blankets, no positioners. This is the single biggest proven way to lower the risk of sudden infant death.

Jaundice

Normal: Mild yellowing of the skin and eyes appearing on day 2 or 3 and fading over one to two weeks is very common, especially in breastfed babies.

Not normal: Yellow within the first 24 hours of life (always urgent), yellow reaching the belly or legs, yellow deepening instead of fading, or a yellow baby who is too sleepy to feed. Jaundice plus sleepiness is the combination I never want watched at home - the full jaundice guide is here.

Crying

Normal: One to three hours of crying a day in total, often bunching up in the evening, peaking around six weeks. Some of it has no findable reason. That is not failure - it is a newborn's only language doing overtime.

Not normal: A high-pitched or weak cry that sounds wrong to you, crying that is inconsolable for hours with a drawn-up body, or crying with fever, vomiting or a swollen abdomen. Your ear for "wrong" develops fast and deserves respect.

The cord, the skin, the visitors

The cord stump dries and falls off in one to three weeks; keep it clean and dry, fold the nappy below it, and skip the home remedies on it. Redness spreading onto the skin around it, pus, or a foul smell means a doctor today. Newborn rashes - little white dots, blotchy red patches, peeling - are mostly cosmetic and pass. Limit visitors in the first weeks, ask anyone with a cold to admire from a distance, and make hand-washing the entry fee for holding the baby. Nobody loving will mind.

The three rules that outrank everything above

  • Fever is the big one. A temperature of 38°C or more in a baby under 3 months means see a doctor the same day - do not give fever medicine first, and do not wait for morning. Full guide here.
  • Feeding is a vital sign. A newborn who stops feeding well is telling you something. Act on it early.
  • Your unease counts. If the baby looks wrong to you in a way you cannot articulate, that is enough reason to be seen. I would always rather check a well baby than hear about a sick one tomorrow.

Everything else - the hiccups, the sneezes, the startle that throws both arms out, the crossing eyes - is a newborn being a newborn. Enjoy the parts you can. This month is long and short at the same time.
