Guaria MontessoriBefore Guaria, there's Baby Guaria.
Free, guided activities for children 0–15 months — simple things you can do together at home, before your child's first day with us.
A philosophy, not a checklist
The sensitive period that shapes how a child learns doesn't start at 15 months — it starts at birth. From day one, your child's brain is building the architecture that will shape how they think, learn, and connect for the rest of their life. This process unfolds in stages, each one opening a new window for a different kind of growth.
Baby Guaria follows this natural unfolding. Rather than giving you a library of activities to browse, we send you one guided activity each month, chosen specifically for your child's current stage of development. Each activity is simple — a few minutes, no special materials — but intentional, designed to gently nurture the same foundations that Guaria's four-pillar method builds upon:
The earliest seeds of concentration and self-direction — the roots of Montessori.
Building the neural pathways for communication and, later, the flexibility that comes with a second language.
Nurturing natural curiosity — how your child learns to observe, explore, and reason about the world.
The first experiences of pattern, music, and movement — the foundation for auditory and mathematical wiring.
How it works
You sign up with your child's birth month
This is how we know exactly which stage your child is in — so every activity arrives at the right time.
Each month, you receive one activity by email
Short, clear, and designed for your child's current age. No overwhelm, no backlog — just the next right thing.
You do it together, in your own time
A few minutes at home. No special materials. The activities are simple because the real ingredient is you — your presence, your attention, your voice.
As your child grows, the activities evolve
What starts as following your voice becomes exploring textures, then making music, then early independence. Each stage builds on the one before.
The stages
Your child's first fifteen months are a remarkable journey. Here is how we think about the stages — and what each one makes possible:
0–3 months: Connection
Everything begins with the bond between you and your child. In these earliest months, your voice is the most powerful tool you have. When you narrate, sing, pause, and respond, you are teaching your baby that communication is a two-way exchange — the very first foundation of language and trust.
4–8 months: Exploration
Your baby is reaching, grasping, and beginning to make sense of the physical world. This is when sensory exploration matters most — not flashy toys, but real textures, sounds, and objects. The brain is learning to categorize, compare, and pay attention. These are the earliest roots of scientific thinking.
9–12 months: Agency
Your child is beginning to move independently, to choose, to initiate. This is the window where the seeds of concentration and self-direction take hold — when a child discovers they can act on the world, not just receive it. Simple choices and open-ended play become the foundation for the independence that Montessori cultivates.
13–15 months: Integration
Everything comes together. Language is emerging, movement is purposeful, rhythm and pattern are becoming part of how your child understands the world. All the foundations you've been building are ready to grow further.
Free in-person activities in Newton
Baby Guaria isn't only at home. Throughout the year, we host free, open activities for families with young children in and around Newton — a chance to meet other parents, experience our approach firsthand, and let your little one explore in a warm, prepared environment.
As a Baby Guaria member, you'll be the first to know when these events are happening — so you can save a spot.

Guaria Montessori (15–48 months)
If you enjoy this approach and want to continue it beyond the home, Guaria Montessori carries these same foundations forward for children 15–48 months — personalized Montessori, immersion in Spanish, scientific discovery, and music on real instruments, all in a small classroom led by Ms. Lili.
