I’m travelling for work (nurse said this was okay). 15-month old had her vaccines on the 17th December. 2 days ago she developed the very high fever they mention can happen. She now has a very mild rash which doesn’t seem to bother her. We’ve had some incredibly hard nights though. Last night it was her worst night ever — worse than when we had actual flu and other things. She was up all night screaming and unable to fall asleep for very long. Very attached to me at the hip. Just want an idea of how long this might last to mentally prepare myself…
