ADHD and Autism in Motherhood: Why So Many Women Are Only Diagnosed After Having Children

(ADHD and autism in motherhood explained)

Last year I wrote about autistic motherhood and late identification — how many women move through life “holding it together” until parenting shifts something. (Read Here)

Now, new data from Centre of Perinatal Excellence (COPE, 2026) confirms this is more than a pattern observed in the therapy spaces, it is a significant statistic that warrants more support and screening during the perinatal period.

• 62.2% of neurodivergent individuals didn’t know they were ADHD, autistic, or AuDHD until pregnancy or early parenthood
  

• 90.9% said parenting was more challenging because of their neurodivergence
  

SO. If you’ve ever found yourself googling:“Why does motherhood feel harder than it should?”“ADHD symptoms worse after having a baby” “Could I be autistic as a mum?”

You’re not alone and this data helps explain why.

Why during parenthood/motherhood?

What I see clinically — and what we’re now seeing in research — is that motherhood exposes neurodivergence. We know that parenting can push you to your limits, however for neurodivergent parents (especially those who are not aware of their neurodivergence)

Parenting places sustained demand on areas like:

• executive functioning (planning, organising, starting tasks)

• sensory processing (noise, touch, sleep disruption)

• emotional regulation under fatigue

• managing unpredictable routines

These are the exact areas impacted in ADHD in women and autism in women, particularly in those who have spent years masking.

So when parents often feel defeated and 'different in their parenting experience', it's more helpful to consider “What’s changed about the demands on my brain?”

While the statistics from COPE were specific to mothers, I also want to make a point that many men who go under the radar in their childhood ( due to masking, specific interests considered gender appropriate, career tied to interests, appear disciplined in their routine with hobbies i.e. meal planning and sports) are typically not identified until their child presents for an assessment. Parenthood leaves very little room for masking!

Why this gets missed (and misdiagnosed)

A lot of mothers present with:

• postnatal anxiety

• postnatal depression

• burnout or “mum overwhelm”

And while those diagnoses can be valid, they don’t always explain the full picture.

If someone is experiencing:

• sensory overload from constant noise or touch

• difficulty initiating everyday tasks

• mental fatigue from tracking multiple demands

• a need for structure in an unpredictable environment

…then we need to consider undiagnosed ADHD or autism in adulthood.

Otherwise, people end up trying strategies that don’t quite fit — and blaming themselves when they don’t work.

Why so many women are only diagnosed after having children

This is one of the most searched questions right now:“Why was my ADHD/autism missed as a child?”

There are a few consistent reasons:

• girls are more likely to mask or compensate socially

• traits are often internalised (anxiety, overthinking, perfectionism)

• success in school or work can hide underlying effort

• structure and routine act as scaffolding

• our understanding of Neurodivergence has significantly changed

  
  

Parenthood removes a lot of that scaffolding.

Suddenly there’s:

• less time to prepare

• constant interruptions

• increased cognitive load

• very little recovery time

  
  

So the question shifts from:“Why am I struggling now?”to“How have I been managing all along?”

What actually feels harder in neurodivergent motherhood/ parenthood

This is where people often start searching for answers:

“Why is noise so overwhelming as a mum?”→ sensory processing differences

“Why can’t I keep up with daily tasks?”→ executive functioning load

“Why do I feel constantly burnt out?”→ cognitive fatigue + lack of recovery

“Why do routines falling apart affect me so much?”→ reliance on predictability for regulation

None of this is about being a “bad parent.”It’s about a mismatch between environmental demands and how your brain processes them.

Why early identification matters (especially in pregnancy)

COPE’s findings highlight something important:many women are only discovering their neurodivergence once they are already overwhelmed.

Earlier identification — even during pregnancy — can make a significant difference in:

• preparing for sensory and cognitive demands

• setting up external supports and systems

• involving partners in a meaningful way

• reducing risk of postpartum mental health difficulties

Because when people search: “How to cope with ADHD as a new mum” What they often need is not more strategies —but a different understanding of their needs.

Support for neurodivergent parents isn’t about doing more.

It’s about:

• reducing mental load (not adding to it)

• externalising organisation (lists, shared systems, visual supports)

• adjusting expectations around capacity

• understanding sensory thresholds

• creating structure where possible

• widening the village where possible

  
  

And often the biggest shift is this:

Understanding why things feel harder.

That alone can reduce a huge amount of shame.

For me, the takeaway from this isn’t just about parenting.

It’s that we’re identifying neurodivergence too late — particularly in women.

If most people are only discovering this in pregnancy or early motherhood, then we’re missing earlier opportunities for:

• screening

• support

• psychoeducation

• prevention of mental health decline

And that has ripple effects across families.

If you’ve found yourself wondering:

• “Do I have ADHD or autism as a mum/ dad?”

• “Why does motherhood / parenthood feel so overwhelming?”

• “Why did everything get harder after having a baby?”

It’s worth exploring whether neurodivergence might be part of your experience.

Not as a label —but as a way of understanding your brain with more accuracy and less self-blame.

If this resonates, I share more about neurodivergence in parenting, late diagnosis, and supporting your nervous system in real-world ways through the clinic and resources at Thriving Young Minds.
