Full Day Toddler and Preschool


Massachusetts Horticultural Society

Mostly outdoors, ages 15 months through 6 years


Drop-off is outdoors at Massachusetts Horticultural Society (MassHort).  The address is 900 Washington Street, Wellesley, MA.

We spend our days in the forest and gardens.  The children are active participants in selecting which places we visit and how we explore them.  Click here for a video of the extraordinary gardens at MassHort.

Our classroom space is located in MassHort's Education Building, right down the hall from the library.  The large classroom space is bright and airy, with 16 windows.

We can accept up to 9 toddlers (ages 15 months through 2 years and 9 months) and up to 10 preschool children (ages 2.9 years through 6 years) in our full-day program.  Each class has two teachers (4.5:1 ratio for toddlers and 5:1 ratio for preschoolers).
