I have been in a similar position as you brightsparks. I had a dcg who, no joke, would have loose poop 4-6 times per day. It was ridiculous and even though I hinted several times that I thought she was drinking too much milk he parents never did anything about it. And when I say too much milk, I am talking 2 8 oz bottles per day at my house and probably 2-3 more of those at home from what I heard. She was twelve months and really that is just way too much milk. Finally, I told them around 18 months that we needed to cut down on milk because it was making her a picky eater. I always serve food before milk but if she didn't like what was served, which was most of the time, she would sit and wait for her milk. So her diet was pretty liquid. Finally when we cut back the pooping dropped dramatically to 1-2 per day. It is SO frustrating though to be in a position where you KNOW something is wrong and have a pretty good idea why but the parents a) don't seem to care or b) are too lazy to do anything about it.
