I used a heat pack for my backpain and cs wound. I also got one of those nifty 'claw' type things you use to grab stuff thats out of reach. Not sure what its called but it was so handy since I was on my own at home and in a lot of pain. A really great pillow would also be nice, I wished I had one post-birth. Will add more if I think of it. Can't believe you're so close now! Time flies!
Or a basket to keep things like the TV remote, books etc... in without having to get up & down all the time.

I was very fortunate to have DH home for approx. 3 weeks, then my mum for another two. I was then alright on my own.
