heimisheyid,
tzippi is unfortunately right. Budgeting alone does not always make the expenses become less than the income. Sometimes you need to figure out a way to increase the income in addition to decreasing the espenses. Its not that easy though. Maybe your wife can get a job, maybe you can find a higher paying job, start a side business or get a part time job for the evenings or sundays etc.
I’m not trying to downplay budgeting though. No matter how much money a person makes it will never be enough if they don’t budget.
