The odor from the bag definitely will get better with time. We tried using the M9 drops but afer about
2 weeks, the odor really went away. we stay away from anything gassy, (which also gives him stomach cramps) and stay with a lot of carbs, pasta, potatoes, chicken. We also stay away from most milk products, but my son does tolerate Yogurt smoothies without much gas pain.
But it will get better!! Keep the faith!
