I convinced DH to buy me a body pillow (you know the ones shaped like a candy cane) - It took up half the bed and pushed DH out the other side - I didn't like not being able to feel him there - so I used to end up chucking it on the floor - BUT - it was a fanastic breast feeding aid!

I didn't like having a pillow between my knees - I realised I actually sleep with my hands there! I just wedged a normal pillow under my back and that helped - too much stuff in the bed made me feel a bit hemmed in!
