Can my next child also have Developmental Trauma?

If one child carries the weight of early adversity, it is natural to wonder whether your next baby is destined for the same — and the reassuring truth is that this is not something passed down like an inherited gene.

In short

Developmental Trauma is not a genetic or inherited condition, so it does not pass automatically from one child to the next. It arises from a young child's lived experiences — early adversity, disrupted caregiving, neglect, loss or repeated overwhelming stress — rather than from DNA. That means each child's story is their own, and a safe, nurturing, predictable environment is the single most protective thing you can offer your next baby.

Understanding why it happens

Developmental Trauma describes how a very young child's developing brain and stress system adapt to early, overwhelming or unpredictable experiences — not something written into their genes at conception. So the honest answer to your worry is: no, your next child does not "inherit" it from a sibling.

A few things are worth understanding gently:

• It is experience-shaped, not gene-determined. Two children in the same family can have very different early stories — different pregnancies, different caregiving moments, different events — and so very different paths.
• Shared circumstances, not shared genes, are what matter. If the difficult conditions that affected your first child (for example illness, separation, household stress or instability) are still present, they could affect a younger sibling too. The good news is these are things that can be changed and supported.
• Protective care is powerfully effective. Warm, responsive, predictable caregiving — being a "safe base" your baby can return to — actively buffers a child's stress system and builds resilience.

So rather than asking "will it be passed on?", the more helpful question is "what can I put in place so my next child feels safe and secure?" — and that is something well within reach.

When to seek a check

If you are pregnant or planning, and your family has lived through significant stress, it is wise to talk with a paediatrician or developmental clinician early — so support is in place from the start. For your next child, watch over the first years for how they settle, soothe, connect, play and respond to comfort. If any little one seems persistently distressed, withdrawn, or hard to console, a gentle developmental check brings clarity and peace of mind — never to label, but to support.
