Night feedings/comfort nursing

Addie

Our son is breastfed, bedshares, still nurses at night... the whole 9 yards. I want to start weaning, starting with night feedings but I need advice. He's currently sick with a cold and desperately wants to comfort nurse (banging his head into my boobs, spitting pacifier out, pulling at my shirt). Should I wait until the cold passes to start weaning? And how you cope with weaning a child who only sleeps by nursing? lol
