i found this thread useful, to make up a list of things that were necessary and things that would be luxuries (so to speak).
hope it helps...
"have you bought anything that was a waste of money" thread
i got loads of basics shopping around supermarkets, i.e. packs of clothes, own brand toiletries
nappies on offer (3 for 2 in boots and then points to buy other bits with) use points systems (join pampers, bounty, boots, tesco preg/mother clubs you get sent money offer vouchers, some crap, some useful) and shop around for everything. NOT store cards, just loyalty.
ikea have some reasonable stuff such as baby bath, bibs, fleece blankets, flannels, high chair and very reasoanble cots.
also i bought some packs clothes at boots when they were buy one get one half price (bought various sizes) and they were doing a triple pionts weekend- so got loads of points to buy other stuff.
make a list of essentials and keep checking it when you are shopping around, that way hopefully you won't miss out on any bargains that would be useful to you. and won't get tempted by things you don't need.
also Primark for clothes in a size or two up for maternity wear - i just got basics to last for now and until i can get back into my regular clothes. have been able to get by with some of DH slightly older basic clothes like Tshirts/fleece. with a coat on who's going to know if your wearing the odd bit of mens wear??
I found it hard to ask, but got friends and mum to ask people they know who had babies last year about stuff they may want to sell or give away. As long as they are tactful, like saying we'd rather get it from someone we know, or you know how babies grow so quickly is seems so wasteful to keep buying new, the shops make so much money out of new parents.. etc. this worked for me, got virtually new crib, newborn nappy packs that never got used, a few clothes, second hand high chair.
oh and when shopping on ebay spell brand names slightly wrong when searching, as some people make those little mistakes when listing, and sometimes you can pick up a bargain that way, as other watchers don't see it. (does that make sense?)
Anyway hope some of this helps.
oh and don't panic! just be practical and organised and shop around everywhere for new and used.
goodluck
