we were horrible with money with our first bub :S But we were also pretty lucky because we got given pretty much everything we needed. Including months supply of nappies.
We are also pretty lucky here because we get around $5000 (AUD) when we have our first baby and $3000 (AUD) for all other bubs.
We have a pretty good budget now including all our bills, food, clothing, birthdays, xmas, etc.
For this bub specifically we are planning on using around $1000 of the money we get from the government on a good double pram and carseat. $the rest will probably go towards getting ahead in all our bills.
For bub when he/she arrives,
I plan to put away $10 (AUD) a fortnight into a bank account under bubs name
$40 a fortnight for nappies and wipes
$10 a FN for clothing allowance
$20 a FN for birthday/christmas
We already have most of the stuff we need for bub from our last baby, especially if this bub is a boy as well.
