I would wait until you are sure she is completely well and then do the sleep training again. Unless you do not have a problem with co-sleeping that is really personal choice. Unfortunately no matter how well a child normally sleeps illness, teething, can all disrupt that pattern and sleep training may have to be done all over again. She probably just realizes that now if she cries she can come into your bed and that is what she wants. Most babies will start transitioning into one nap a little over a year old but even that is a process because some days it works and others it doesn't. If you don't want her sleeping in your bed then I suggest you wait until she is completely well and then start the sleep training process again. Good luck and I hope you get some sleep soon.
