Christy, I know what you are going through.
We went through this with DD2 when she was 4 with bacterial meningitis.
Just watch her closely this winter as she may pick up every bug that is going as their immune system is lowered due to the illness. Not sure if this happens with viral.
For yourself, get some rest as you will need it in the next week or so as she starts to improve and reaction sets in.

If you can get by with out the lumbar puncture that's great. Thankfully we didn't have to have one as the culture showed a positive reading.

A word of warning with anyone who thinks that their child may have it, they don't always get a rash or vomit. The main signs are a temperature that climbs and eyes that are sensitive light. If in doubt, don't leave the hospital or Dr's until you are ready. If I had left when I was told to we would not have our DD.

All the best with her recovery (and yours)
