Early signs of developmental trauma in 18-to-24-month-olds

When a little one has lived through frightening or overwhelming experiences, their behaviour and body often carry the story before they have words — and noticing gently is the first act of healing.

In short

Early signs of developmental trauma in an 18-to-24-month-old can include intense and hard-to-soothe distress, clinginess or withdrawal, disrupted sleep and feeding, easy startling or 'freezing', and a wobble or loss of skills they had already gained. Many of these overlap with ordinary toddler ups and downs, so pattern, persistence and context matter most. Only a qualified clinician can tell apart a passing phase from trauma-related distress that needs support — this list is for gentle awareness, never self-diagnosis.

Early signs to watch for

Around emotions and connection

• Crying or distress that is very intense and hard to comfort, even from a familiar caregiver
• Becoming unusually clingy and fearful, or unusually flat, withdrawn and 'switched off'
• Watchfulness or wariness around certain people, places or sounds
• Strong distress at separation and difficulty being soothed on reunion

Around the body and routine

• Disrupted sleep — frequent waking, nightmares, or great difficulty settling
• Changes in feeding, appetite or tummy upset with no clear cause
• Startling easily, 'freezing', or a body that often seems tense and on alert

Around play and development

• Losing skills (words, play, toileting steps) they had recently gained — a developmental wobble
• Repetitive, joyless or 'stuck' play, sometimes replaying a frightening theme
• Less curiosity, exploration or shared delight than before

These signs are not about a 'difficult' child or 'bad' parenting — a young brain under stress is doing exactly what it is built to do to stay safe. With the right support, that same brain is wonderfully able to recover.

When to seek a check

Brief unsettled spells are part of toddlerhood. Seek a developmental check when these patterns persist over weeks, appear across settings, or follow a known stressful or frightening event — such as separation, a difficult medical experience, loss, or major upheaval. A clear loss of skills, or your own steady worry, is reason enough to ask. If a child ever seems unsafe, unwell or in physical danger, that warrants prompt medical attention rather than waiting.
