i think you've been given some really great ideas!

i think if it were me, id be trying to pay extra off the bills, and also stock up on basics (disposables if thats what you're using, wipes, perhaps even baby clothes up to size 1) and then find out what entitlements you will receive, and maybe make a budget and start it, using your 'new income' amount, and putting away the rest.

i also love the idea of buying coles vouchers... i plan to do this with my tax return and baby bonus instalments.

good luck with it!
