We co-sleep with our daughter who is also 2. While I might not take my temps at the same exact time each morning, I don't think it has mattered much. I can still see my temp shift and can see a clear pattern from month to month. My biggest problem is finding my bbt! She likes to pretend its a knife and "cut" things with it. I usually keep it put up until I go to bed, and then after I temp, I place it on my computer so she can't erase the temp. Good luck...I believe that it can be done
