Family systems and stress
A research-based look at what surrounds a child, from couple dynamics and siblings to work, childcare, and chronic stress, and how the family as a system shapes a child’s nervous system and long-term development in ways individual interactions alone don’t capture.

Free to join. A note when the class opens, with early access, and an occasional research note in between.
By the end of the class
You’ll have a clearer picture of the family as a whole system. Clear about what’s known. Honest about what’s not.
- How stress, conflict, and emotional tone travel through a family and what children’s nervous systems absorb from the environment around them.
- What the research says about the adult partnership, and how it shapes a child’s experience of security.
- What sibling conflict is actually practicing, and how it develops real social competence.
- What the research says about childcare, separation, and parental availability, including what it can’t tell us.
- What protective factors actually look like: the specific things that help children develop well inside real, imperfect families.
Six modules
They zoom out from the individual to the whole family.
-
Module 1
The Family as a System
How stress, conflict, and emotional tone travel through a family, and what children’s nervous systems absorb from the environment around them, independent of what any single adult does in any single moment.
-
Module 2
Couple Dynamics and Parenting
What the research says about how the adult partnership, its quality, its conflict style, and how partners support each other, shapes a child’s day-to-day sense of security and long-term development.
-
Module 3
Sibling Relationships
What sibling rivalry and conflict are actually practicing, how fairness works developmentally, and how siblings develop real social skills, like negotiation, empathy, and repair, by working things out with each other.
-
Module 4
Childcare, Work, and Separation
What the research says about quality care, separation anxiety, parental availability, and the realistic limits of what any family can provide, without the guilt that surrounds working parents.
-
Module 5
Chronic Stress and the Developing Brain
What prolonged household stress, whether financial, relational, or logistical, does to developing brains, what the ACE research actually shows, and what protective factors buffer children from its effects.
-
Module 6
Repair Across the Family
What to do after hard stretches like conflict, stress, and rupture, and how families recover. Why repeated repair over time builds resilience more reliably than any perfect period ever could.

Who teaches it.
Created and taught by Matthew McArthur, who holds an M.A. in Developmental Psychology from San Diego State University, where he studied how parent stress, changes at home, screen time, and back-and-forth interaction shape language and thinking from 6 months to 5 years, after working with developmental researchers at UCLA, and he wrote “Why Early Chatter Matters” for Frontiers for Young Minds.
He then spent two years in state-funded early intervention, coaching families with children under 3 who were experiencing delays.
A few things parents usually ask first.
When does the class open?
This class is in active development. Waitlist members are notified first and get early access before the class opens to the public.
Is this class relevant if my child is older, or if I’m a single parent?
Yes. This class is designed for any age and any family structure. The research on family systems applies whether you have an infant or a five-year-old, whether you’re partnered or parenting solo. The content is framed around how families actually look, not an idealized structure.
