Bring baby along and maybe walk pass the IFC (if they hve windows to view) before deciding which school to enroll. Then you can see what are the babies / teachers normally doing. Sometimes teachers will engage with you if they see you at the window. Then you can talk to the teacher and see if the IFC is good. Usually if teacher try to engage with you even before you join, it’s a good sign because this means if your baby goes to the school, the teachers will probably give a lot more updates xx
