I've started taking my temp any time i wake up in the night, so i can get in the habit of doing it. Problem is my son has been waking up a lot. I sometimes get 4 hours at a time. But not always... my temps are all over the place too. In one night i got temps of 98.89 and 98.0. How can it very so much. I'm using all my old tricks, vaginally temping to try to get things more even... but its not working
