Baby refused to nurse for 2 days suddenly, except once middle of night. I though he had teeth pain or weaning. Then the 2nd night he wanted to nurse all night every hour so I assumed the nursing strike is over and he is making up for not nursing. Nope, next day he refused to nurse again. At night he nursed only once when asleep. Next day nope no nursing, even when I offered expressed milk...then at night he went all boob crazy and is waking up to nurse every hour. Then sucking and won't let go.
