Hi my 16 week old has been unsettled for 2 weeks. She's had periods where she hasn't fed much and seemed to struggle to feed, generally been unsettled for Kong periods of day and night, and hasn't gained as the health visitor would have expected her to. Tonight she had a nappy with little black specks in it. I have called NHS direct but just waiting for them to call back but could take up to 4 hours, in the meantime I'm really worried and wondered if anyone might have any suggestions
