Our son has been at Rainbow daycare since he was 18 months ( he is 5 years old now). At 18 months, he barely said 2 words, however, after 2 months, kid would not stop talking. Lora worked intensively with him to ensure proper pronunciation of sounds. We receive many complements on clarity of our sons speach. All instructions, daily activities, concerts are tought in Russian. Our son just transitioned to kindergarden and Rainbow daycare has prepared him very well for it. In 2 weeks of school, our son is conversing in English, however, we continue private Russian language lessons with Lora. The owners provide such a nurturing, loving, caring and educational environment, that we are very fortunate to have them in Sharon. We would highly recommend this daycare.
