Havemercy,
As a mother of three, grandmother of four and fellow 'worry wort', I've had my fair share of fear and foreboding.
Unfortunately, our anxieties have a way of turning up in our dreams. As grandchildren multiply and grow up relatively unscathed, you eventually realize the futility of all that needless worry.
Keep in mind that the internet has a way of magnifying the frequency of the most dire incidents, as do the movies and television. It may ease your mind to know that in spite of all the alarmist news reports, the statistics are still in your favor.
That means that regardless of all the media hype, your grandchild's odds of averting foul play and living to a ripe old age are more likely than not. So, congratulations, be optimistic that everything is going to be OK and enjoy your beautiful, new grandchild!
