Most strange newborn symptoms are normal physiological transitions from life inside the womb to the outside world. You're likely looking at a standard part of development that doesn't require a medical intervention.
You're sitting in a quiet room at 3am, watching your baby sleep. Suddenly, they stop breathing for six seconds, or their chin starts trembling, or you notice a strange orange stain in their diaper. Your heart rate spikes. You're wondering if you should call the hospital or if this is just how babies are. Most of the time, it's just how babies are.
1. Periodic breathing (the scary pauses)
Newborns don't breathe like adults. They have an immature respiratory system that leads to "periodic breathing." This means they might take several shallow, rapid breaths, followed by a pause of up to 10 seconds. Then, they take a deep breath and return to a normal rhythm.
It's terrifying to watch if you aren't expecting it. As long as your baby's skin and lips stay pink and they resume breathing on their own within that 10-second window, it's normal. Their brain's breathing centre is simply learning how to regulate itself while they sleep.
2. The Moro reflex (the sudden startle)
If you've ever put your baby down in their bassinet only for them to throw their arms out, arch their back, and scream, you've seen the Moro reflex. This is a primitive survival reflex. It's an involuntary response to a feeling of falling or a sudden noise.
It looks like your baby is having a tiny seizure or is in pain, but they're actually just reacting to a change in position or sound. This reflex usually peaks in the first month and disappears by four or five months. If you find it's waking them up constantly, a snug swaddle can help dampen the movement.
3. Milia (tiny white pearls)
You might notice tiny, hard white bumps on your baby's nose, chin, or cheeks. These are milia. They look like whiteheads, but they aren't acne. They're actually small pockets of skin flakes trapped near the surface of the skin.
Don't squeeze them. Don't scrub them. You can't wash them away, and trying to pop them can cause an infection or scarring. They'll clear up on their own as the top layer of skin wears off, usually within the first few weeks of life.
4. Urate crystals (the "brick dust" diaper)
Finding a pink or orange-red stain in your baby’s diaper is enough to make any parent panic. It looks like blood, but it's usually urate crystals. These are concentrated salts in the urine.
It’s common in the first few days when your baby is only getting small amounts of colostrum. Once your milk comes in and the baby’s fluid intake increases, the urine becomes more diluted and the crystals disappear. If you're seeing this after day five, it’s a sign to check in with a lactation consultant or your midwife to ensure your baby is getting enough milk. You can find more details on these types of symptoms in the Newborn Symptoms A–Z guide.
5. Crossed eyes
In the first few weeks, your baby’s eyes might wander or cross. They haven't yet mastered the muscle control required to focus both eyes on the same spot. It might look like they have a permanent squint or that their eyes are moving independently.
This is normal for about the first three months. If the eyes are constantly crossed or if the wandering continues after four months, it’s worth mentioning to your doctor, but early on, it’s just a lack of coordination.
6. Constant sneezing and snorting
Newborns are obligatory nose breathers, and their nasal passages are tiny. A single piece of lint or a drop of milk can cause them to snort, whistle, or sneeze repeatedly. It doesn't mean they have a cold.
Sneezing is simply the only way they can clear their nose. Since they can't blow their nose or clear their throat like we do, they sneeze to get rid of dust, hair, or dried mucus. Unless they have a fever or are having trouble feeding because they can't breathe through their nose, the snorting is just noise.
7. Baby acne and cradle cap
Around week three or four, your baby's skin might break out. It looks like teenage acne, red bumps and whiteheads. This is caused by your hormones still circulating in their system. It's not a reaction to your diet or the laundry detergent.
Similarly, you might see thick, yellow, crusty scales on their scalp. This is cradle cap (seborrheic dermatitis). It's essentially baby dandruff. Neither of these conditions bothers the baby. They aren't itchy or painful. Most of the time, leaving them alone is the best medicine.
8. Swollen breasts and mini-periods
Both male and female newborns can have swollen breast tissue. Some might even leak a tiny bit of milk (sometimes called "witch's milk"). Female newborns might also have a small amount of bloody vaginal discharge in their diaper during the first week.
This is purely hormonal. They've spent nine months bathed in your hormones, and as those levels drop after birth, their bodies react. It's temporary and will resolve on its own within a few weeks as the hormones leave their system.
9. Peeling skin
If your baby was born a little late (past 40 weeks), they might look like they're shedding their entire outer layer of skin. Their hands and feet might peel significantly. This is because the vernix, the white, waxy coating that protected their skin in the womb, was absorbed or washed off, leaving the skin exposed to the air.
It doesn't hurt them. You don't need to peel it off or slather them in lotion. Underneath that peeling layer is perfectly healthy, soft skin. It's a normal transition from a liquid environment to a dry one.
10. Jittery chin and twitchy movements
You might notice your baby's chin trembling or their limbs twitching rhythmically while they cry or sleep. It can look like a tremor. Because their nervous system is still developing, the electrical signals in their brain can be a bit "noisy."
A jittery chin during a crying spell is almost always normal. If you can stop the twitching by gently holding the limb or putting your hand on the chin, it's just a normal newborn tremor. If the twitching continues even when you hold the limb firmly, that's when you call your doctor.
11. The pulsing soft spot
The fontanelle, the soft spot on the top of your baby's head, is where the skull bones haven't fused yet. It's covered by a thick, protective membrane. You might notice it pulsing in time with your baby's heartbeat.
This is completely normal. You're seeing the blood pulsing through their system. It's also normal for it to bulge slightly when they cry or strain. What you want to watch for is a soft spot that is deeply sunken (a sign of dehydration) or one that is bulging when the baby is calm.
12. Explosive hiccups and yawning
Newborns get hiccups all the time. They can last for 10 or 15 minutes and often don't bother the baby at all, they might even sleep right through them. Hiccups are caused by a slight irritation or contraction of the diaphragm.
They also yawn frequently, even when they aren't necessarily tired. Like sneezing, yawning is a way to regulate their system and take in more oxygen. If your baby is having trouble with sleep despite these normal cues, you might find our 2am troubleshooting checklist helpful.

When to call your provider
While most things are normal, there are specific thresholds that require a call to your midwife or doctor. This is education from a postpartum doula, not medical advice; your provider knows your history.
- Fever: Any temperature of 38°C (100.4°F) or higher in a baby under 3 months old is an emergency. Use a rectal thermometer for the most accurate reading.
- Dehydration: Fewer than 6 wet diapers in 24 hours (after day 5), a deeply sunken soft spot, or a dry mouth.
- Breathing Distress: If the pauses in breathing last longer than 20 seconds, or if you see the skin sucking in between the ribs (retractions), nostril flaring, or blue/grey discolouration around the lips.
- Lethargy: If your baby is too sleepy to wake for feeds or seems unusually floppy and unresponsive.
- Persistent Jaundice: If the yellowing of the skin or eyes is deepening or moving down toward the legs.
You will never be in trouble for calling your provider to check. It's better to get a "everything is fine" than to sit at home worrying. If you want to be prepared for what to look for, the Postpartum Warning Signs guide covers these thresholds in more detail.
FAQ
Why does my baby make so much noise while they sleep?
Newborns are incredibly noisy sleepers. Between the periodic breathing, snorting, grunting, and whistling through their tiny nasal passages, they can sound like a small zoo. This is usually due to their immature respiratory system and doesn't mean they are distressed or sick.
My baby's poop is bright yellow and seedy. Is that okay?
Yes. Breastfed baby poop is typically mustard-yellow, loose, and has a "seedy" texture. Formula-fed poop can be a bit darker and firmer. As long as it isn't hard like pebbles, black (after the first few days), or white, the colour range is quite broad.
Is it normal for my baby to twitch in their sleep?
Yes. This is often "sleep myoclonus." Their nervous system is discharging energy as they move through sleep cycles. As long as you can stop the movement by touching them or if it stops when they wake up, it's not a cause for concern.
My baby sneezes five times in a row every morning. Do they have allergies?
It's very unlikely. Newborns don't typically develop seasonal allergies. They sneeze to clear out the dust and lint that accumulates in their tiny nostrils overnight. It's a sign that their clearing mechanism is working well.
It eases. It really does.
