How can you ask for his money?

After you get married and have a child. How did you deal with your own household financial?,do you always ask some money from your husband?(even if you’re a career woman). How did you do that?(ask directly,already in promise,his own awareness,or else),do you always depend on that?,do you think that is his necessary responsibility?(many wives will ask 75% from their husband’s salary). If yes,how much will you ask?(do you think he’ll agree with you?).
