I am a fan of the stretchy cotton wraps too.......useful as wraps or as cosy blankets. Pumkpin Patch do large 1m x 1m ones, or you can just buy the fabric from Spotlight by the metre and hem it yourself.

Charlie was a winter baby, and at night I would have him in a singlet, a Bonds suit, wrapped in stetchy cotton wrap, with another stetchy cotton wrap over the top.

Also remember yourself in the middle of the night getting up to a baby in winter! Have your slippers ready as well as something to put over your shoulders........I even had a mohiar rug to drape over my knees......so I was all warm & toasty for those night feeds........Charlie and I would fall back asleep together in the chair.....so cozy.......
