If you can't resolve the medical situation, then there aren't too many choices. ONe is to swap at least one of the toilets to a Caroma - personally, they aren't as nice as the Totos, but they do have the biggest trapway of any readily available toilet on the market. While not the nicest thing, you can keep a supply of throw-away paint stirrers and chop it up before trying to flush it, or live with it as it is. With some people, adjustments to their diet can make a big difference but that's harder to get young children to follow. As an inexpensive experiment, try two heaping teaspoonfuls of Metamucel before going to bed mixed into a full cup of water. Double-check with the doctor, but this may resolve the problem. I've tried some of the other products, and found them to just make things harder, but this stuff holds a fair amount of water and keeps things soft (but not runny). It does help. May not be the answer, but won't hurt, isn't expensive, and might. Makes it less traumatic when away and then clog someone else's toilet, too.
