Great suggestions I added a little bit of stuff to my weekly shop, so I maybe bought a pack of 3 white vests for £3.50 (Asda or Tescos) in the shop one week, the next week a pack of newborn nappies etc...little things usually less that £5 a week so you don't notice it as much!
Baby wipes Tescos own are just as good as all the rest! and the pack of 4 for under £4!
Tescos own brand nappies are fine if your using disposables, infact Aldi nappies won awards (I've just potty trained my dd1 so I didn't get a chance to try them but number 2 on the way I am going to give them a shot).
Sign up to Aldi & Lidl newsletters they often have baby stuff for now and later on offer.
Sainsburys/Tescos/Asda always have baby weeks so you can usually pick up bargains there!
Also another vote for all the baby clubs I'll list them at the bottom of this post I've joined loads!
Personally I had more than 7 sleep suits/vests so I did less loads of washing!
Another vote for carboots/jumbles/charity shops/nct nearly new sales.
Also speak to your midwife our Health centre collects things for young mums they have a young mums group, and I gave a few bits to them new and 2nd hand (in good condition) they goto young families like yourselves.
Ref housing benefit in Nottingham you have Metropolitan Housing which are a housing association, HA rent is usually cheaper especially if you are getting housing benefit (when you check), contact them if they don't cover your local area they will be able to advise who does. As a young family you get a higher priority than a single person on the waiting list.
They also have support workers who maybe able to help you claim more benefits/grants.
CAB is also another good stop to get advise on local grants/assistance available.
Some councils/areas have toy librarys so as baby gets bigger you can "hire" bigger toys for £1 a week or so! A great way to try before you buy!
You might find your able to complete your course next year as often Colleges have schemes including free child care places...
