I can't believe it - 6 hours after they said we would be in for a while, they changed their minds, took her off one lot of antibiotics and sent us home. She is now snuggled up in her cot, happy as larry!
She has to have antibiotics administered every day by a home care team, and has to go back for a check up on Tuesday, but at least she is home.
Now she can relax. She can sleep through (hopefully!) without anyway taking her temp etc.
Thank you again for all your words of comfort and support.
