My daughter is 14 weeks old and suffers really bad from reflux. I have her on aptamil comfort milk and carobel thickener. The last week she has developed diarrhoea. The comfort milk is supposed to help with constipation so I wasn't sure if it's this that's caused it. I always find the gp, no matter who I see isn't that helpful with her, it's like they don't really know what they're doing. I wasn't sure wether to wean her over to the normal infant milk, although it has more lactose in it so could cause problems. Has anyone else experienced anything similar?
