Worrying about Attachment Difficulties at 12–18 months

If your toddler seems hard to settle, or oddly unbothered whether you come or go, it is loving — not over-anxious — to ask what is normal at this age.

In short

At 12–18 months, Attachment Difficulties (ICD-11 6B44) are rarely something to "diagnose" — this is exactly the age when secure attachment is still actively forming. Most clinginess, separation upset, wariness of strangers and seeking you out when frightened are healthy, expected signs that the bond is working. What deserves a gentle clinical conversation is a persistent, marked absence of seeking comfort, or strikingly indiscriminate warmth towards strangers — especially after disrupted early care. None of this is a verdict on your parenting.

What is healthy at this age

Between 12 and 18 months, you should expect — and welcome — behaviours that can look like "difficulty" but are signs of a secure bond forming:

• Separation protest — crying or clinging when you leave
• Stranger wariness — checking your face before warming to new people
• Comfort-seeking — coming to you when hurt, tired or frightened
• Using you as a base — venturing to explore, then returning to "refuel"

These are reassuring, not worrying. A child who does all of this is doing exactly what nature intends.

When a gentle check makes sense

Consider a developmental conversation — not alarm — if, across weeks and settings, your toddler:

• Rarely or never seeks comfort from a familiar caregiver when distressed
• Seems consistently flat, withdrawn or emotionally absent
• Is strikingly over-friendly with strangers, with no checking-back
• Shows these patterns and has a history of disrupted or interrupted early care

These point to patterns worth observing, not a label. Much settles with predictable, warm, responsive caregiving.
