My Granddaughter is on her way

My daughter-in-law's contraction has started they are 15 to 20 mins apart. I"m so excited. I was down at the hospital earlier today and she was doing fine they had started her prep and she was comfortable. I asked my son if he wanted me to go down and he said not right now I told him to call if he needed me. I can't believe he's going to be a dad. He's nice and calm right now doing good I'm so proud of him. He's staying the night with her which is good.
I just tried to call my mum and the phone cut out. I reception is the pits. I'd hate to have an emergency
