This isn't really in Makati, but if you want to go beyond the city, try Kindermusik. They have a class in BGC and I heard Kindermusik classes are really fun and informative. I've watched one activity when my wife and I attended an event. We're thinking of enrolling our kid there soon. They said they're the world's leading music and movement program for kids below 7 years old. http://www.kindermusik.com.ph/index.html
Playworks Makati (formerly Toddlers and Teachers) os great for kids ages 0 - 5. I have family members whose children went there and they had nothing but good things to say! They have a website, but I believe that since the name change, the whole venue is under new management. You'd be better off checking out the FB page. I'll link it below! https://www.facebook.com/PlayworksMakati/
