For couples with baby/ies living with their in-laws (husband side), how do you make "pakisama" with them? Do you give monetary "thank you"? Are you in charge of the food, utility bills, give them allowance etc? How do you effectively manage your finances if all of a sudden you'll be in charge of 2 more adults. I'd love to hear how you sail through this situation because we're currently in that situation and I'm having difficulties about it.

You just have to emphatize with them. You don't necessarily have to give them monetary "thank you" but you have to give your fair share for the utility bills and other stuffs that you are mutually consuming by living with them. This where the problem always start, so if you think you are consuming more of (for example) the electricity then add a little bit more to your share of the bill. It's all about being sensitive to their needs also without neglecting your own. Always be respectful, learn how to effectively compromise, help with the chores.. stuff like that. They will appreciate that in the long run. :) ^
