Awww try not to beat yourself up over this Her temp could have spiked really quickly in a short time. You did what you thought was the best thing under the circumstances and I would have done the same thing - there would have been no reason at all to suspct a UTI would there? The main thing is that when she did get really sick, you took her to the ED and got help for her and she's going to be fine OK Thats not being a bad mummy at all.
