DD was born during a heatwave so I used those giant bamboo muslins from Aden and Anais as light blankets/swaddled. They were expensive but one of our most used baby purchases! Useful to take out and about as they are so useful as somewhere to lay the baby down or as a sun shade. I still often chuck one under the buggy for the toddler in case it gets chilly during the summer.
For general sick mopping I used cheap supermarket muslins, lots of them! Also useful if you have big boobs for breastfeeding,I used to shove one under my boob to lift it up a bit. Oh the glamour.
cinderella I had a Moby stretchy wrap for newborn, they are nice and thick so will be good for a February baby. We also have a Manduca carrier which we used until DD was about 2, another brilliant purchase! Got it in plain black so DH was happy to use it too. I think he carried DD more than I did actually!
