One year in but a newbie

I got a call from my youngest about 3 this afternoon. She believed she had broken her toe and no one was home. I went over immediately. I asked her where her medical card was so I could take her to hospital. She said her mother had it and she had tried calling and texting her. I tried as well and got no answer either till about 6 pm. She was on a date. She was mad that I did not take daughter to hospital. I told her it was not life threatening or i would have regardless of where card was. I asked her to leave copies of the cards in the future so I would be able to handle these issues without her being bothered.

what do you do with a WAS if they are so busy getting their own life that they can ignore text and phone calls from a multiple of their kids? How do you respond to this?
