What would you do if your kids aren't handling Manila summer well? Any tips on how to help then get through this heat?

I suggest lots of water, juices and you can even make home made popsicles! If you live in a house with a yard, bring out the inflatable kiddy pool for them to splash around and have supervised water fights. I remember playing in the park with my brothers and dad during the humid June holidays as a child and having mock battles with water guns. Dad would make sure we were dry before going home so Mom won't scream haha.
