My main concern for you and your babe is hydration. I picked up a norovirus a year or so ago. I came very close to going to the ER due to dehydration. Lost 6 pounds in 2 days. I drank a lot of broth and Gatorade. Fiber supplements are fine to thicken, but avoid slowers because you need to shed the virus.
If your urine becomes concentrated or you become dizzy, go to the ER for IV hydration. The good news is that this resolves almost as quickly as it ramps up.
