DS (2.5) had single mumps jab about 3 weeks ago and ever since he has had on and off diarrhoea. I thought it had gone but it was back today. he's fine in himself and is eating normally. Has anyone else experienced this? I'm a bit worried it's damaged his gut - is this possible does anyone know.
Don't relish thought of taking him to docs and getting the "well what do you expect' type response.
