I've not read the whole thread, so this might have been said, but ask if you can borrow things off people. Anything really. Ask people at work. I borrowed steriliser, moses basket, high chair, clothes, car seat, baby walker. A few things they said we could keep, so was a bonus.
You don't need to have everything brand new. Baby items are ridiculously expensive, and it's an expense you don't need when you have to buy nappies, and baby food.
Look on Facebook buy and sell groups, I've bought clothes from these. They literally last a few months and they grow out of them anyway, so what's the point in paying full price for Next or Adidas. Or if you have a local car boot go to that. I've bought clothes as new for 50p each.
