cordless phone - what a godsend.
dishwasher - don?t know how I manged without this for DD1.
washerdryer - drying baby clothes without a tumble dryer in winter when they get through so many outfits a week is hard work.
plenty of easy ready meals in freezer. Internet food shopping is also very handy with a new baby.
nice relaxing quiet music for settling baby (and you) down for sleep can be a god send
don?t buy too many of those baby "help" manuals if you can help it - it can be so confusing and stressful as they often offer such opposing advice that you can be left even more confused than you started. Either buy one that seems to fit into your way of thinkg (eg. strict routine or baby led more flexible ideas) and remember that it is only worth following if it works for you or don?t bother at all and go with your instincts and advice from places like mumsnet, health visitor or friends with young children.
babybjorn front carrier - (bought cheaper model for DD1 and regretted it - spent the money for DD2 and carried her easily in it for 6 months)
baby monitor for peace of mind (plenty of threads about which one - very subjective and emotive topic it seems)
decent change bag - don?t need to spend a fortune but worth getting one that has waterproof lining, several large poskets to divide up wet wipes and nappies from feeding stuff, change of clothes, toys, puse etc etc. Nice comfy wide strap because it will weigh a ton when loaded up. Also look at the opening latch - one with complicated catch and loads of zips will drive you mad when juggling a wriggly baby and hunting through a bag one-handed.
plenty of cot bedding incl. a waterproof backed base sheet to protect your matress. Most babies regularly mess up their cots one way or another and on a bad day if they are bringing up a lot of feed you can change your cot bedding three times or more.
plenty of support - friends, family, partner, whoever, just as long as there is someone around to help out. Worth joining a mums and babies group . I didn?t do this with DD1 as it all just felt too stressful to contemplate (very shy) but made the effort with DD2 and have not looked back - it is my lifeline.
HTH and good luck - when is baby due?
