I'm to be a Nana again!

I'm so happy to find out today I'm going to be a Nana to a 2nd grandchild. It's very early days.
Sadly my daughter lost her 1st baby at 13 weeks ( she found out on a dating scan). Luckily she fell pregnant very quickly after surgery, and my beautiful grand daughter now 2 and a half arrived.
I'm so apprehensive though history might repeat itself. Having had 4 miscarriages myself after my 2nd child it was devastating to watch my child go through the awful agony of loss. I didn't go on to have anymore due to a blood condition.
How to get through the next 12 weeks again. With my granddaughter it was such a deeply intense, stressful time, but of course I never let on to her because she was so frightened to lose again.

I'm so happy right now though - say a little prayer for this new little life.
