HollyM gave you some great advice there.

Can you borrow clothes off someone? You will be surprised how many people will be willing to help out a mum to be. Babies grow out of clothing so quickly

I think DD, only wore like a couple of bond suits for her first few months.

Always hunt for bargains and do a price match thing (ie go to a store ask for the price and then see if another store can offer lower)

Agree, dont need the best of everything, prams can cost from $100 to $1000!!! get one that is reclinable but also one that is light for when your baby becomes a toddler. I got mine from ebay brand new steel craft transition for $170 (free delivery)

Kids dont need expensive toys. DD's fav toys were maracas i made with plastic bottle and rice and I made her her own touch and feel drum which she still uses today and she's 17 months.

Also, you dont need to get everything at once. for example with a high chair, just wait until you see a mega cheap bargain (sometimes Toys R us has them for like up to 80% off!!!)

Best of luck with everything and enjoy your journey to motherhood =)
