DS, 2.5, has had pretty runny dirty nappies for about 3 weeks. They haven't increased in frequency, and I wouldn't call them diarrhoea, but I'm starting to worry about it a bit. Thinking about taking him to the doctor, but I know he'll scream the place down and I'm not sure if I want to put us through it for not much. I wouldn't worry so much, but he's already pretty skinny and the health visitor has us in her (evil) sights over it. He does eat, or as much as any two-year old does from what I can gather. The only change in his diet that I can pinpoint is an increase in chocolate consumption over the Christmas period. Am wondering if this might have a laxative effect. Didn't give him any yesterday, but doesn't seem to have made a difference yet. I know you guys aren't doctors (well, statistically, some of you must be!), but I'm wondering if others have experienced similar and how long you'd let it go on. Ta.
