Is separation anxiety a normal part of child development?

When your little one cries the moment you step away, it can tug at your heart — but more often than not, this clinginess is a sign of healthy attachment, not a problem.

In short

Yes — separation anxiety is a normal and expected part of child development. It usually appears around 6–9 months, often peaks between 10–18 months, and gradually eases through the toddler and preschool years. It actually reflects something healthy: your child has formed a strong, loving bond with you and is beginning to understand that you exist even when out of sight. For most children it settles with gentle, consistent reassurance.

Why it happens — and what's typical

As babies grow, they develop object permanence — the understanding that people and things still exist when they can't be seen. Knowing you've gone but not yet trusting you'll return is what triggers the distress. This is a developmental milestone, not a setback.

Typical signs include:

• Crying, clinging or fussing when a parent leaves the room or at drop-off
• Wanting to be held more, especially when tired, unwell or in new settings
• Wariness of unfamiliar people, easing as familiarity grows
• Settling within minutes once comforted by a trusted carer

These ups and downs often flare again around big changes — starting daycare, a new sibling, or travel — and that too is normal.

When a gentle check helps

Separation anxiety is rarely a concern on its own. Consider a developmental check if, well beyond the toddler years, the distress is severe, long-lasting and stops your child joining everyday activities like school or play — or if it comes alongside delays in talking, playing or connecting with others. A check simply tells apart ordinary clinginess from anything that would benefit from a little extra support.
