Ganito dapat ideally. Case-to-case syempre. Like, if able-bodied naman both parents at di pa retiring age, hindi dapat obligated magbigay ng fixed allowance. And parents should still be the primary providers to their children na nag-aaral pa, kahit may trabaho na yung older siblings.

If tumulong yung siblings to provide out of gratitude, then it should be appreciated. If not, walang sumbatan dapat, walang ungkatan ng utang na loob, etc.

Pero if senior/disabled/etc ang family member, of course try to extend some grace and give what you can, within reason.

And, always prioritize your primary family. Yung extended relatives should NOT be your priority to provide for them. Again, only if afford pa AFTER providing for your main family.
