my 5 week old is having 1-3 runny green poops a day. i am switching to formula feeding and still givi g her breast milk a few times a day. i use enfamil. does this look like a normal poo or diarrhea? could it be she is allergic to the formula. she is also spitting up after every feeding and i have difficulty burping her
