Want to have a happy family? Have 2 girls / daugher

Was skyping when a friend told me that a survey was done and that apparently a family with 2 daughters is the happiest?
I was like ..Serious boh?  Happiest..perhaps it true also lah..just that we never did ever realise it until someone pointed it out..
But then it does also has it fair shares of siblings fights, jealousies and what nots while they were growing up..

but one thing is true though..you save on clothes, hair accessories with hand me downs..!!
I know..kam siap me again counting $$$$
louve you girls
have nice weekend
