My baby is 10 months old next week, she's had diarrhoea since Monday night, several very runny nappies a day and smells very bad! Like vomit! Spoken to the health visitor who says it can be caused by teething, she got her first two teeth, the top two with no problems, she now has quite a few coming through at once and her cheeks are red, she's not sleeping as well at night, apart from that she's still her usual happy self, it's just this upset stomach that's worrying me. Does anyone know if it's normal?
