She is probably really busy, Grammy. I would say she might have spent over 2 hours at the vet, getting everything ready, getting the section done, getting Alice woke up, after care instructions, etc.
Then she has to get home, get them inside and all settled, and make sure everyone is eating and ok. She would be weighing and doing her data sheets, and IDing every, etc.
I'm sure everything is just fine, she's just busy. Might not hear from her until in the morning.
