Do you give fix monthly allowance to your parents/inlaws?

Yes I do. Since my little family stays with my parents, for me it's my responsibility to give a fair share to our house bills and expenses. What I share is actually more than enough to cover all our bills and groceries for the month but it's fine since my mom is also the one who looks after our daughter. Also, it's my way to help them save as sooner or later my partner and I will for sure separate from them and live our own life. And so before that happens I know they can sustain their "senior years" already and enjoy and hopefully finish their own house in the province - their dream place to settle for. :)
