CJ's mommy,Kefir grains
are a symbiotic 'colony' of bacteria and yeasts that can culture or lacto ferment milk, or milk like products.Kefir, the drink
that is formed from it, is /usually
/ cow milk based, but can be from a variety of milks or milk like products.
These 'grains' can also ferment 'sugar water' or juice solutions, and make a drink often refered to as "Kefir d' Aqua". There are also special 'Kefir grains
' designed to 'live' in the sugar water solutions (called Water Kefir grains
It sounds like your son's allergies (sensitivities/condition) have a pretty serious affect on him, so I'd avoid any milk (cow, goat, etc).
That being said, yes you can 'culture' soy milk, coconut milk, juice, almond and rice milk. Here is the Dom's link on making those things, with very detailed instructions: (first link is overview, second link has soy and nut or seed milk recipes, third link has some general brewing instructions)http://ftp.newave.net.au/~dna/kefirp...ternativekefirhttp://users.chariot.net.au/~dna/vegmilk.htmlhttp://users.chariot.net.au/~dna/Mak...#Kefir-d-acqua
Here is a website I just found that has ALOT of recipes for making lacto fermented beverages.http://www.rejoiceinlife.com/recipes/index.php
The main reason to ferment these products is to increase the 'good' bacteria and yeasts in your digestive system. So, if you find that making or buying these products isn't your thing, remember, there are good capsule forms of probiotic suppliments you can buy for your son.
I think they would benefit him, sans milk and I would say, sans soy, as it's been argued it can cause some of the symptoms your son is having. If your son is eating whole wheats, nuts or seeds in any form, I would also suggest you look into 'soaking' them to help digestability and remove ANY forms of intestinal irritations.
I'm not a doctor, it sounds like his situation is pretty serious, so I'd suggest you also consult with your pediatrician or a child's nutritionist to find some other good (AND SAFE) ways to introduce these beneficial bacteria into his digestive system. I not familiar with MSPI and would hope that the 'capsule form' of probiotics would be ok for him to consume....sometimes even things 'grown' in a known irritant (cow milk) can cause a reaction. So please check with your doctor.
:HUG and best wishes. I hope you find a form of probiotic that's safe for him to eat/drink. It might actually help rebuild and restore his digestive system enough to be able to better tolerant some other milk forms down the road. I know some mom's have said their child could NOT drink cow milk from the store, but raw milk was fine. I've no experience here...but it might be worth looking into.
