Children grow up way too fast. But at Stellabella Toys, everything slows down—at least long enough to free the inner child—in as many parents as kids. More of a play studio than a toy store, this expansive space in Inman Square is stuffed with educational resources for child-rearing. The colorful dolls, storybooks, science kits, and costumes are displayed in a space that’s big enough to also fit a playroom and a toy house kids can climb on. The store hosts playgroups for infants and toddlers, family yoga, new-parent meet-ups, and musical get-togethers. With its strict no-guns-for-sale policy, this is more than just a neighborhood toy store: It’s a mini enclave of enlightenment.
