i am so sorry for your situation. How did your baby get it? did she have all her shots or did she contract parvo before she was done with her series?
im sure your baby will be fine since she is getting IV fluids which is very important so she doesnt dehydrate...here is a link that tells more about it...i think your baby have a better chance than 50%...i real they have more like an 80% chance of survival.
