Dianne I feel for you, I am having the same problem with Trilly and Frank, and I am at the end of my tether... don't know what to do anymore. Her getting sick again is the worst of all my fears.
It looks like Emma and Trilly have the same biological clock, and they won't give up! Usually Trilly goes back to non-eggy at the beginning of January and I am counting the days... I hope your Emma will stop being so determinate soon too.
