We went there from 18 months to 3 years. We're transitioning to DCPS now (primarily because of proximity to our in bound public school). The teachers are phenomenal and care deeply about each child. We have nothing but good things to say about our experience in the classroom itself. Admin is a different story - not terrible, but little to no transparency and communication with parents. All said, I would definitely recommend Estrellitas to friends/family who are looking for a montessori-style approach to childcare.
