Re. Chat above on baby bits:
sleeping we were given a Moses basket to use for DS1 and I just bought a new mattress for it (about £10). He slept in it til about 16 weeks but was quite a small baby. I think 12 weeks more usual. He was only in our room for 3 nights then in his own room as I found him too noisy and couldn't sleep 
we lived in a flat though and kept doors open so were literally no more than 5-6 steps from him all the time. Never used our monitor. We've now moved to a house so DC2 may stay in our room longer or we may move into their room and use the monitor-i'm open to see what we want to do.
bed we also bought a cot bed which DS1 still using as a cot and can then convert to a toddler bed. We have also been given a digger toddler bed though so we will keep DS1 in cot with sides up as long as possible to prevent wandering and then move him into his new room with the digger bed and his mattress, get new mattress for the cotbed and pop DC2 in there. Hopefully this will all coincide around Oct/Nov time when DC2 ready to leave Moses basket!
pram etc this was our most expensive purchase! We bought a 3 wheeler Zoom travel system from mamas and papas. It has been great. We used it predominantly with the car seat attached until DS1 was 6m-so convenient for popping out! Make sure you get a raincover for the car seat though-despite heat wave when DS1 born we first used it when he was 2weeks old while friends were messing around with draping blankets! Our system was v easy to manoeuvre and had huge basket for storage which was great-never carry shopping again :). It did also come with a carrycot attachment which I confess to only ever using twice as DS1 not keen - he preferred being cosily snuggled in the car seat and was too hot to bundle him up to be cosy in the carrycot. At 11months we were heading on holiday so I got a second hand umbrella-fold style pushchair and have used that ever since as it's narrower to get on buses etc and has better sunshade. However I loved having DS1 facing me in the big pushchair as we could chat as we walked places!
bouncer chair IMO one of the best things I got was my babybjorn bouncer. DS1 did a lot of his daytime naps in it to start with a loved chillin in it watching what was happening. I could easily keep him with me when he was in it and even take him into bathroom if I wanted to have a bath or shower! These chairs are expensive but we got ours second hand from eBay and was in as new condition. They hold their value so I will sell on when we're done with it.
change bag lastly and something that's quite personal yo you but a great thing to ask DH or DM to treat you too! I really struggled to choose as I like leather handbags but opted for an OiOi one in the end (as a treat-def had more money then!!). But the Pacapod ones are probably some of the best-search online and if you like things organised then you will probably fall in love! I have a 'changing pod' I use in my bag and it's so so handy.
Sorry for the super long post. Hope some of it is useful! I found a spreadsheet, lots of research and deciding which were the items I was most opinionated about helped me prioritise spending! Happy planning! Oh and finally I set up a gift list on John Lewis website so could direct people there if they asked what we needed-much easier than trying to remember what you said to who!
Now wonder if I can get back to sleep
