I just got caught up with your situation. I can understand the wait is hard. But remember the more you are nervous and the more you are stressed Lizzy will sense it and that is not what you want right now. You want her to be calm so she can have these babies. here are some links to calm you down I hope you can get a nap in as previously stated the end of the week could be the time. keep us advised. This is a natural situation and Lizzy will know what to do when it is time.
