Do the constant hospitalizations ever end?

My 3 year old was diagnosed in December, and is currently hospitalized for the 3rd time since due to low blood counts. I understand it can take a while to find the “right” biologic (already failed off of Remicade due to elevated liver enzymes), but is being in and out of the hospital so often normal after a new diagnosis? Does life go back to some semblance of normalcy if you find a medication that works? My heart hurts seeing her so so sick. She’s such a sweet, brave girl. Both asking & looking for support/words of encouragement. Thanks :)
