My 2 yr old son has suffered with respiratory problems most of his life. He has had 2 prednisone 5 day doses(just in October alone)and respirator treatments albuterol 4x day and pulmocort 2x day for 6mo with little relief. Everytime he gets a cold he wheezes and his breathing rate increases. I wanted to try anything. He has been on probiotics for 1 month and has not been sick once and this is November!!! I am so hopeful this will work for the long term. When I was pregnate with him I had a sinus infection for 8 weeks. The put me on several antibiotics that were supposedly safe but I wonder if they messed his good bacteria up in his gut. I highly reccommend this product for any child that is chronically sick.
