Yes, sleep and antibiotics have certainly helped. Raine was MUCH more herself today, eating normally, and wanting to play with her friends. We're not rushing that last one, so she was kind of disappointed. Oh well. Her foot was much improved today, looking much less red and swollen. Even the fever has gone down. The IV dose of antibiotics should give her system time to build up the oral one she's taking and hopefully we won't have it flare up again.
I'm not one to rush to the emergency room for every little thing, but if she would have had to be so miserable and sick and all for 24-48 more hours until the antibiotics really kicked in... well, I'm thinking we got positive feedback that we made the right choice.
