I am not sure if the spec ex ones that can digest milk come back. . .but the accidophilus (pease like I can EVEN think about spelling that. . .I need an asprin!) bacteria. . that digest the milk sugars in milk to make yogurt. . .are some of the good bacertia that natural yogurt gives you. .. I had C-sections with all my kids and nothing help thrush fluorish like antibioctic! And the only thing that ever worked on my kids were power accido(go laugh at the other way I spelled it) powder and whole milk Stoneyfield Farm yogurt and air. . .cleared it on both ends. . .that Nyastin (sp again) stuff never touched it. . . .wouldn't a nice bowl of whole milk yogurt (be sure to mix it. . .the SF yogurt has cream on the top) strawberries and a little splenda and vanilla. . .makes a great breakfast! And helps your colon and tastes like it is bad. . .but it's good for you in many ways. . .! redawn
