There is no single timeline that applies to every child. Duration depends on how quickly the triggering infection was identified and treated, how rapidly immune-directed treatment began, how many prior episodes have occurred, and the severity of the current episode. Some children recover substantially within weeks of appropriate treatment. Others have a longer, more uneven road with partial improvement and setbacks. Recovery is often not linear — some good days followed by harder ones does not mean treatment isn't working. Children who receive appropriate treatment earlier tend to do better than those whose treatment is significantly delayed, which is one of the strongest reasons early recognition matters. Small improvements — better sleep, fewer raging episodes, more food acceptance — are real progress even when full recovery feels far away.
