I can't say this with scientific authority. My experience is 18 years managing health food stores and all I had to learn to do it. But that supplement, LactoFlora, isn't one that would be recommended for your child. For one thing, you say he as a dairy allergy. Actually, most humans can only digest mother's milk anyway, but a few ethnic groups do have the enzyme necessary to digest animal milk as adults. LactoFlora has milk in it. Second, it's taken with food. Probiotics have to bypass the stomach to really work, that's why the best ones are in enteric capsules or liquid that contains so many organisms that some will get into the intestinal tract, which is where probiotics live. Once they move in, they should stay there; if they keep disappearing, that would indicate something going on that's causing a die-off. One possibility is a chronic candida yeast infection. Another would be if too many sterioids or antibiotics were used. But still, eventually, one would hope the organisms would permanently lodge in the intestinal tract again. The prebiotics are good, they are sugars that provide food so the body can feed its probiotics. What's working is the bifidus, the beneficial bacterium most beneficial for the intestinal tract. You might want to try the Bifidus formula from Nature's Way. It doesn't have the prebiotics, but it's got two types of bifidus instead of just one, and doesn't have the dairy problem.
But the fact this is fading in effectiveness, and the fact something that on its face doesn't look to be a very good quality product (always be careful about direct marketed products -- and this one says if you don't refrigerate it, it will degrade. It doesn't degrade, the organisms die if unrefrigerated because they aren't in a place they can live. Under refrigeration, they will hibernate until they find a nice home. But it does have the prebiotics, so at least while it's being shipped they have something to eat. I just don't trust direct marketed products -- always wonder why they avoid the judgment that comes from trying to get into stores, past suspicious knowledegeable eyes like mine) -- for your son and it worked anyway suggests a possible placebo effect that's wearing off. I assume you've been to doctors to get this diagnosed? Naturopaths are good at treatment, but don't have the diagnostic tools a gastroenterologist has. I usually tell people, get diagnosed by a doctor, then get treated by a naturopath for digestive problems. (Doctor's treatments usually make it worse in the long term with rebound effects of the medications they use).
Good luck.
Acid reflux is worse when laying down.
It sounds a lot like my daughter, but all of her symptoms were when she was a baby. She would not gain weight always crying, poor thing she was miserable. We were in and out of the doctors office. She woulf vomit often to. Finally after all the test, they ran one more and it turned out that her small intestine was malnutritioned. You are suppose to have these things in your intestine to sock up the nutrients but hers was just nubs. So after about 3 months of tube feeding her she is complely normal. But they would have never found it out if they did not put her to sleep and get tissues from her stomach and intestines. Hope I have helped..
