    Inside Nido I

    Everything designed around your child.

    1:3 infant · 1:5 early toddler — rare, low ratios

    One dedicated adult for every three infants, and one for every five early toddlers, so your child always receives personalized attention, care, and affection.

    Close communication with you

    Crawling, first words, first steps — we celebrate every milestone and stay in close contact so we're always doing what's best for your child. Through our Transparent Classroom platform, you can follow updates and moments from your child's day.

    Peace of mind

    Rigorous staff background checks, CPR/First-Aid-trained teachers, and a comprehensive emergency plan — every detail considered for your child's safety. We also use Transparent Classroom to stay in touch with parents and share information on your child's day.

    An environment made for infants & early toddlers

    Low rails to pull up on, soft mats, custom floor beds for sleeping when tired, and low shelves of beautiful, sensory materials in a calm, homelike room.

    Trust through consistency

    A five-day schedule means the same familiar guides and friends every day. Sleep and feeding follow your child's own rhythms, carefully observed and shared with you.

    Trained infant specialists

    Nido guides are trained in child development from birth to 18 months — a career of choice, chosen out of genuine love for our youngest learners from infancy through early toddler years.

    The next stage

    The Early Toddler Stage

    At the early-toddler stage, children are discovering their bodies. We teach regulation, awareness of space, and independence — sitting in a circle, washing hands, taking shoes off and on — in preparation for the next step. A lot of learning happens in early toddler.

    Questions & answers

    Frequently asked questions

    What ages is Infant & Early Toddler for?

    Infant & Early Toddler serves infants from about 3 to 18 months.

    How are infants cared for in a Montessori setting?

    In a calm, prepared environment with a low ratio and trained caregivers, infants are free to move, explore real objects, and build trust and independence at their own pace.

    What does a Montessori infant room look like?

    Low, safe spaces for movement, natural materials, mirrors and bars to pull up on, and simple, beautiful objects — everything scaled to an infant's real capabilities rather than plastic toys.

    Infant spaces are limited, so we recommend reaching out early. Schedule a tour or call (623) 935-7737 to check availability.
