Hi Kittytat,
I get newsletters from SimpleSavings... they have lots of great hints and tips.

I get paid each fortnight, so I work out everything in fortnights.
I've created an Excel spread sheet with formulas that breaks all the expenses into weekly, fortnightly, monthly and yearly expenses. I re-calucaulated the amounts so that I know how much I need each fortnight to pay everything for the year. I have everything on there from make-up, clothing, presents, entertainment etc as well...
I also get money from each pay to go directly into ING (bank), it takes 12-24 hours for the money to be put into my everyday account, so it reduces impulse buying.
All the best with the new bubby...
