Hi Grace786,
Welcome to Doha! I have a three yr old son whose very happy at Starfish Lane, he's currently in their summer programme and is having great fun. The staff are enthusiastic and the kids enjoy being there. My son was at Creative Child at Reviera Compound but the teachers were v sleepy, even disinterested and he was always getting sick. I'm not sure about the Montessori school but their number is 444 5655. Good Luck
