Every baby cry carries information: pitch, rhythm, length of the pause between wails, and what the body is doing while it happens. Parents who learn these four signals respond correctly far faster — and babies who are answered faster cry less overall.

You can shortcut the learning curve with our free Baby Cry Analyzer: record five seconds of crying and it classifies the most likely reason for you.

The five cry sounds (Dunstan sound patterns)

These reflex-based sounds are clearest between birth and about 4 months.

| Sound | Means | What it sounds like |

| --- | --- | --- |

| Neh | Hunger | Tongue pushes to the roof of the mouth — a rhythmic "n" sound at the start of each wail |

| Owh | Sleepy | Mouth ovals into a yawn mid-cry, long and drawn out |

| Heh | Discomfort (nappy, hot, itchy) | Short, sharp, irregular bursts with jerky movements |

| Eairh | Lower wind / gas | Deep, grunting, straining, legs pulling up |

| Eh | Upper wind / needs a burp | Short repeated "eh" bursts, often mid or post feed |

The four signals to read

1. Pitch

Low to mid pitch usually means a need — hunger, wind, nappy. Sudden high pitch signals pain. A shrill, weak or moaning cry is a medical red flag and needs a doctor now.

2. Rhythm

Rhythmic and repetitive with even pauses = hunger. Continuous with almost no pauses = overtired or overstimulated. Sudden bursts with silence between = pain or gas spasms.

3. Build-up

Hunger cries build slowly. Pain cries start at full volume with no warning. Tired cries start whiny and escalate.

4. Body language

• Rooting, hands to mouth → hunger
• Legs drawn to chest, tight tummy, arching → gas or reflux
• Turning the face away, clenched fists, red eyebrows → overstimulated or tired
• Whole body stiff with a scream out of nowhere → check for a hair tourniquet, an insect bite, a nappy pin, or illness

A 60-second decoding routine

Listen for 5 seconds — rhythmic or continuous? Low or shrill?

Look at the legs, hands and face

Check the clock — when was the last feed? How long has baby been awake?

Feel the back of the neck for temperature and the nappy for wetness

Respond with the single most likely fix, and give it two full minutes before switching

Switching soothing techniques every 20 seconds is the most common mistake. Most methods need 90–120 seconds to work.

Does cry analysis actually work?

Sound classification is a useful prompt, not a diagnosis. Studies of cry acoustics show pain cries are reliably distinguishable by pitch and onset, while hunger and discomfort cries overlap more. Treat any tool — including ours — as a first guess that you confirm against the clock, the nappy and the body language.

Cries change with age

• 0–3 months: reflex sounds, mostly hunger, wind and tiredness. See baby crying causes 0–3 months
• 3–6 months: more intentional; boredom and teething appear
• 6–12 months: separation anxiety, frustration, and crying used to call you
• 12 months+: communication and emotion, less reflex
