Hello, my 6 week old breast fed son has had diarrhoea for over a week and green stools for longer than that. He is straining much of the time, day and night, passing small amounts of green/yellow watery/bubbly liquid poo at every feed and sometimes more often. He's also in pain with the straining, and has obvious tummy pain, which isn't confined just to the evening. He often wakes up crying with it. I've cut out cows milk and it's not making any difference so far. I'm not sure what else it could be? I did have a course of antibiotics myself so wondered if that might be the cause, but finished a week ago and dS seems if anything to be getting worse not better. Any advice??
