Lately my dd has been refusing to take her bottle, she gets between 4-6 ounces 1 hour after her solids, about 3 times perday sometimes 4, i have to give her a late night bottle to make up calories. She ha been pulling this the last week, should i worry about it or is it just a phase?? I know it could be a nursing strike but that would make this her second one in the last month or so. She takes her solids fine, can i just assume she isn't hungry?
