The "heh" cry is the Dunstan Baby Language sound linked to physical discomfort: too hot, too cold, a wet diaper, a scratchy tag, an awkward position. It is short and breathy, with an audible "h" at the front. Treat it as a listening cue rather than a diagnosis: independent research has not confirmed these sounds map reliably to specific needs.
It is easiest to catch in the first seconds of fussing, before the crying builds. A small clue, not a verdict, but a small clue is enough at 3am.
What the "heh" cry sounds like
Instead of a long, rising wail you get short bursts with air in them, as if each cry is pushed out on a sigh. Parents often call it scratchy, or a cry that catches at the start.
- A breathy "h" at the front. It opens with an audible exhale rather than a clean vowel: heh, not eh.
- Short and stop-start. Heh... heh... heh, with small gaps, rather than one continuous cry.
- A sharp, strained edge. Almost startled, as though something just brushed your baby's skin.
- An irregular rhythm. Hunger cries build steadily; a "heh" comes and goes, often flaring when your baby moves.
- Fast escalation. Discomfort does not resolve itself, so a mild "heh" can become hard crying within a minute.
It rarely arrives alone, so watch the body too: squirming, kicking one leg free, arching away from your arm, skin flushed or mottled. Cry plus restlessness is a stronger signal than either alone.
Listen in the first few seconds
All the Dunstan sounds live in the early, reflexive part of a cry. Once your baby is crying hard, the "h" disappears into the volume. If you missed it, nothing is lost; just work through the comfort check.
Why babies make a "heh" sound
The proposed mechanism is a startle-type response to discomfort on the skin. Skin is a newborn's largest sensory organ, and at this age touch and temperature carry more information than sight. When something is wrong there, whether wet fabric, a cold draft or a seam pressing in, the reaction includes a quick catch of breath. Cry over that catch of breath and you get the aspirated "heh."
Discomfort also escalates fast at this age: babies have little insulating fat, cannot sweat or shiver efficiently, and cannot kick off a blanket or move away from a draft. The gap between comfortable and miserable is narrow. Worth saying plainly, though, this mechanism is a reasonable-sounding explanation, not a tested one.
What to do right now: a 60-second comfort check
Work top to bottom, and keep it unhurried.
- 1. Check temperature properly. Feel the back of the neck or the chest, never hands and feet, which run cool in healthy newborns. Warm and damp means overdressed; cool means add a layer.
- 2. Adjust layers first. One more layer than you are comfortable in, in a room around 68 to 72°F (20 to 22°C). Indoors, overheating is the more common problem.
- 3. Open the diaper and look. Do not just feel the outside; modern diapers hide wetness well. A fastener digging into the hip can irritate on its own.
- 4. Hunt for the small irritant. A tag, a seam, a bunched sleeve, a rucked-up sheet, a damp burp cloth, a swaddle tight across the hips.
- 5. Change the position. Upright against your shoulder, tummy-to-tummy, or simply the other arm. Newborns get stiff and cannot fix it themselves.
- 6. Try skin-to-skin. Chest-to-chest contact steadies temperature, breathing and heart rate, and costs nothing to try.
- 7. If nothing changes, move on. Offer a feed. Never delay or withhold a feed to finish a checklist. A hungry baby who is also uncomfortable is still a hungry baby.
The 20-second hair check
If a cry starts suddenly and nothing else explains it, open the sleepsuit and check every finger and toe. A single long hair can wrap tightly enough to cut off circulation, and it hurts. It hides easily under footed pajamas. If a digit looks swollen or dark and you cannot unwind the hair, call your doctor.
"Heh" versus the cries it gets confused with
- "Eh" (needs to burp) is the closest twin, since both are short and clipped. The difference is the opening: "eh" has no breathy "h," and it usually shows up minutes after a feed.
- "Neh" (hunger) is made with the tongue against the roof of the mouth, so it sounds more nasal and insistent. It builds steadily, with rooting and hands to the mouth.
- "Owh" (tired) is rounded and drawn out, shaped like a yawn, alongside eye rubbing and a baby turning away from faces.
- "Eairh" (lower gas) is lower and grunty, with straining and pauses, legs pulled up and released, and a red face.
Honestly, timing usually beats acoustics. Three hours since a feed points to hunger whatever the cry sounds like; ten minutes after one points to trapped air. Use the sound to decide what to check first, not to overrule what you know about the last hour. For all five side by side, see our full guide to the five newborn cry sounds.
What the evidence actually says
Dunstan Baby Language was created by Priscilla Dunstan, an Australian mother and musician, and reached a wide audience after American television coverage in 2006. It is a popular framework, not established clinical science, and the difference matters with a newborn.
Independent, peer-reviewed validation is thin, and what exists has not shown that parents taught the five sounds read their baby's needs more accurately than parents who were not. Acoustic research does find that cries carry real information at a group level, with pain cries tending to start more abruptly and higher in pitch, but the overlap is wide and no five-word vocabulary has been confirmed.
What is well supported is simpler: babies do better when crying gets a prompt, warm response, and parents who listen closely get better at reading their own baby. So treat "heh" as a prompt to look, not a label to trust. If it sends you to check and you find a soaked diaper, it earned its keep. If not, let it go and keep looking.
Not sure whether that was a "heh"?
Record a few seconds with the Babymind AI cry analyzer. It listens and suggests a likely reason, so you start somewhere instead of guessing. A second opinion on a sound, never a diagnosis.

A discomfort cry settles once you fix the cause. These signs do not, and they need a professional rather than a checklist. Call your pediatrician or emergency services for:
- Any fever in a baby under three months (100.4°F / 38°C rectal or higher). Call right away, day or night.
- Breathing trouble: fast or labored breathing, grunting with every breath, flaring nostrils, ribs pulling in, pauses, or blue or gray lips.
- A cry that sounds weak, moaning, or unusually high-pitched.
- Inconsolable crying for hours that nothing you try touches.
- Forceful, projectile vomiting, or vomit that is green.
- Blood in the stool.
- Poor feeding, refusing feeds, or noticeably fewer wet diapers.
- A baby who is hard to wake, floppy, or unusually still.
- Crying that starts after a fall or a knock to the head.
- A swollen or discolored finger or toe, or a soft spot that looks bulging or sunken.
One rule sits under all of it: if something feels wrong and you cannot say why, call anyway. You know this baby's normal, and no clinician will mind.
Most nights the "heh" is exactly what it sounds like: a small complaint about a wet diaper or a warm blanket, fixed in under a minute. Hearing it will not make you a perfect translator. It just gives you a first place to look.
