Being the mom of all girls can be exciting. Especially the drama. So, to keep my sanity I have a rule that I strictly abide by during stressful moments. "Only ONE girl gets to cry at a time. If the baby is crying, then it isn't your turn. When she is done, you may have a turn to cry."
Amazingly this idea works. You have to say it with a straight face and really mean it, though. And when they are all done crying, then it's my turn. But usually by the time everyone is done, we have all forgotten why we wanted to cry and end up laughing instead.
