I know how stressful it is trying to find the right preschool, so you are definitely not alone in feeling unsure! A friend of mine actually sent her child to a Sunflower outlet and she said the teachers were nurturing and quite attentive to the kids, which gave her a lot of peace of mind. It might be worth calling them to arrange a visit so you can get a feel for the environment yourself lah, sometimes seeing it in person makes all the difference.
