How much should I prepare for the hospital expenses when I give birth?

If private, you need at least $15K to play safe. If subsidised, don't have to worry much. I had both before and have thus decided after my #2, go for subsidised for the rest. The only difference is the service rendered while at the hospital and the choice of food.

Minimum of a hundred thousand pesos. When my wife underwent emergency CS and our baby stayed in NICU for a week, it cost us 150,000 +. Better save up for more so you can be ready with emergency cases
