I found a playschool with low student-teacher ratio that can be suited for your kids. Toddlers Teachers Inc in Makati offers curriculum that integrates learning through play. They offer quality education to children from 0-5 years old. They have classes from infant, toddler, extended day and daycare programs and other special classes which you might want to explore.
They accommodate personal tours to families during weekday before 4:00 pm. You just have to call them for a schedule. Below is their website for further details:
