There is nothing worse than a crying baby. Specifically, a baby with colic where no amount of nursing, rocking, bouncing etc., does the trick. When I discovered BioGaia with my second child, I felt like I found a life saver! We breezed through the first few months with minimal tummy discomfort. Bio Gaia is the probiotic bacterium Lactobacillus reuteri. It is a “good” and friendly bacterium that helps battle the “bad” microorganisms in the digestive tract. Fun fact: they found this strain in breast milk and isolated it and patented it!
