If your concern is about finances, you can get a general idea of what you might be entitled to by putting details onto entitledto.co.uk You can put general names like "husband", "me", etc. It's just for your information, it doesn't go anywhere else. See how much you could get if you had a baby tomorrow, for example, or with different incomes.
That said, babies are expensive when one can afford it. Otherwise, they are a cost that can be balance. For example, I did not get a nursery. I got a cot in the sales adding as many discounts I could get, then got old furniture around (wardrobe, chest of drawers). I have always changed them on a mat on the floor. I accepted second hand clothes and baby equipment (steriliser). I bought the cheapest pram I was happy with, and thanks god for that because my DD hated all prams and only wanted carrier. When I could afford it, I bought a second one and made no difference, at least I used for DS. People buy you lots of clothes for the first 3-6 months, you end up usually with a few still with labels. The most expensive baby-related cost is nursery (childcare). If you have family support, you are more than ok. Mine it's about £50 a day, all inclusive, 8am to 6pm. It's a crime, IMO. The rest, are usually one off buys that you might be able to subsidise through family and friends if you explain your situation and start an early baby wish list. Nappies are about £20-£25 a month at its most. I buy pampers and have a subscription via Amazon family (i.e. you can buy cheaper alternatives if it works for you). Baby powder was £40 a month for one year because I couldn't breastfeed, but if you do, that's money saved. I now can use normal. I can't think of any other regular expenses. Wipes, I guess, about £10-£15 a month. Car seat, but if you buy savvy, you could buy those new ones that last until they are 12. You make it as expensive as you can afford, really. It sounds odd, I know, but in the baby frenzy we tend to buy too much and a lot of useless stuff or completely unnecessary. I mean, co-ordinated three or five piece nursery suite is not necessary, the baby does not appreciate it and we mostly do it for visitors (IMO). You can wait and buy a children's bedroom later on. Same with the pram, it's the motherhood equivalent of buying a car (IMO), some people "need" the very foldable super-easy to manoeuvre this year's fashion at £1000+ ... but there are very good ones in the middle range St £300+ and still ok cheap ones around £150. I got mine from the display at Booths, mid -end of September, when they were making room for the Christmas stuff (yep, September...) and the manager just dropped that I could get any display pram for a very discounted price, as they needed them gone. It came down to £60 with car seat and rain cover. Never properly used and perfect condition. There are also lots of car boot style sales throughout the country with NCT, some items are even new. You also get £137 child credit as a minimum, per month. A friend of mine was earning under £33000 as a household and got nursery heavily subsidise plus working tax credits.
Good luck!
