My 4 weeks old has slept 6 hours per night for the last few days, awesome! (she eats every two hours during the day and has plenty of dirty diapers) I got a little engorged but was so exhausted I didn't get up to pump. Today, I have vomiting, flu like symptoms and diareah, and. 100 degree temp. And my boobs hurt! Culd it be mastitis or flu? Has anyone had vomiting/diareah with mastitis? Also, if she is sleeping 6 hours sold I get up and pump ifi feel engorged? Pump a little or empty breast? Thanks for your help!
