Is there any baby fair coming-up in Makati malls?

None that I've heard of. I agree with Rea. If you want to attend baby fairs, you might want to visit nearby cities. However, I believe there are other bazaars, fairs and expos which will be held in Makati area in the next few weeks although they're not baby/family-centric.

I haven't heard of any upcoming baby fair in Makati. Searched online and found these shows instead, if you are willing to go outside the city. - Mommy Mundo ExpoMom the Motherhood Journey (July 2 Alabang Town Center, July 17-18 Trinoma) - 5th Baby, Kids & Family Expo (September 3-4, SM Megamall Megatrade Halls)
