My 4 moth old son has had diarrhoea for the past 12 days since his 16 week vaccinations. He is passing around 8-10 watery stools a day! I have been to the dr several times and sent of an initial stool sample to test for bacteria which was clear. They are now testing for possible inflammation in his gut. I’m just looking for some advice and reassurance from anyone else who has experienced this. I have switched him to lactose free formula and cut out all dairy (on doctors suggestion) and still no improvement.
