If you and your partner are ok, don't bother much about parents anyway.

What happen to me was

I spent RM4k on photoshoot

Then nothing, maybe a few hundred bucks for the JPN registration.

My in laws parents will held their own lunch nearby their hometown restaurant. Cost forked by themselves.

My parents held a buffet dinner. Cost forked by themselves also.

I don't want to mention much as there's so much of stupidity in our culture anyway. Unlike 20 - 30 years ago, all this can be done simple with few k's
Nowadays there's too many young one who overused their quota and even withdraw credit card's money and also borrow from loan shark which cause so many bankruptcy.

Think wisely before spending unnecessary future money lo.

My money all saved for my wife who delivered in private which cost RM11k+
