My family and I will stay at Ortigas in July. Any activities you can suggest that we can do around there with my baby? :)

It depends on your baby's age. Easiest place to visit is Marco Polo Hotel and there, they have a place called Piccolo Kids Club. Just nearby Ortigas, you can take your baby to KidZania if he appreciates role playing. It's a highly recommendable play place for kids.
