Developmental Household System Design
Prepared Home Method™
A developmental transition preparation process
Every family begins somewhere different.
Some are preparing before their baby arrives. Others are navigating a new developmental stage, changing routines, or seeking a deeper understanding of their child.
The Prepared Home Method™ guides families through:
Phase 1
Observation
We begin by understanding your child, your home, your routines, and your caregiving system.
Phase 2
Orientation
Together, we identify what matters most and design a plan aligned with your child’s developmental needs and your family’s life.
Phase 3
Transformation
We prepare the physical environment,
strengthen the caregiving system, routines, and supports needed for meaningful change.
Phase 4
Implementaion
Your family begins living with the changes while receiving guidance, coaching, and support.
Phase 5
Integration
We refine the system so it continues to support your family as your child grows.
About Lizeth
Founder & Developmental Household Consultant
My work is shaped by an integrated understanding of early childhood development, drawing from Montessori developmental theory, infant and early childhood mental health, developmental assessment, and relationship-based clinical practice.
My AMI Montessori 0–3 Diploma (Assistants to Infancy) and Master of Education in Early Childhood Education provide the developmental foundation for understanding the child as an active participant in their own development and the importance of preparing the environment around them.
My training in infant and early childhood mental health, including Child-Parent Psychotherapy (CPP), Harris Infant and Family Studies, and DC:0–5, informs how I understand the earliest relationships as the foundation for psychological development. This work has deepened my understanding of caregiver-child attunement, attachment, regulation, and how children’s experiences are shaped through their relationships and environments.
My background in developmental observation and assessment allows me to look beyond individual behaviors and consider the whole child — their developmental stage, relationships, environment, and the experiences shaping their growth.
Together, these perspectives guide my work with families: supporting them in understanding their child, strengthening connection, and preparing the household conditions that allow development to unfold.
Lumen & Leaf Philosophy
The earliest years of life are a profound period of human development.
From birth to three years old, children are not only learning skills, but also They are constructing the foundations of how they experience themselves, their relationships, and the world around them.
During this period, children are guided by an internal drive toward development. They are absorbing, exploring, moving, communicating, and seeking meaningful experiences within the environment that surrounds them.
Lumen & Leaf provides in-home developmental consultation and prepared-home design for families from pregnancy through age three. We help families align spaces, routines, caregiving roles, and relationships with a young child’s development and the adults caring for them.
The Montessori Legacy
Aristocratic Roots
Montessori was born in Chiaravalle (Ancona), Italy. Her mother's family (the Stoppanis), who were landowners, did possess historical Milanese noble roots, and her father's family descended from Bolognese nobility. Her father was an educated military man who later got into the salt and tobacco business. In 1896, she graduated as a doctor from the University of Rome Medical School. She was one of the first female doctors of her time. Dr. Montessori's work at the Psychiatric Clinic in the University of Rome included bringing in children left in asylums that didn't make distinctions between children and adults at the time to treat them.
Radical work
Dr. Montessori developed one of the first pediatric mental health/developmental clinics of that time. She began to create and test her materials with the children, adding furniture and other materials. She concluded that these children under her care and study didn't have a mental deficiency; rather, they were victims of pedagogical issues. Her revolutionary “Discovery of the Child” brought light to the problems of the traditional education system. She believed that her method was not limited to these children but “ that similar methods applied on normal children would develop and set free their personality in a marvelous and surprising way.”(Standing, 1998, p.30)
Current Impact
Empirical research firmly validates the Montessori method as a premier evidence-based practice. Rigorous scientific studies prove that high-fidelity programs significantly advance child executive function, academic literacy, and social-emotional growth. This developmental impact is extended to early infancy through the AMI Assistants to Infancy 0–3 diploma. A core pillar of this qualification focuses heavily on direct support of the home environment. It trains educators to provide practical blueprints that families can implement in their households. By intentionally structuring physical surroundings, it systematically optimizes an infant's early language acquisition, motor coordination, and daily participation in family life.
The Meaning Behind
Lumen & Leaf
Lumen & Leaf is inspired by Maria Montessori’s insights on Dutch botanist Hugo de Vries's study of caterpillars, which showed their sensitivity to light during a critical growth, guiding them to nourishing leaves. Montessori highlighted that while growth potential exists within living beings, it relies on the right environmental conditions. Lumen symbolizes the guiding force for children, while Leaf represents the nurturing environment. Together, they illustrate how children develop through their inherent potential and the supportive experiences around them.
