Hubby’s grandmother wants play by play texts!?

My husband and I went to a Mother’s Day bbq at his brothers house yesterday and of course we talked a lot about the baby and labor and what not. Before we left, his grandmother mentioned how she wants to know when I go into labor, how far dilated I am, when I start to push, etc. I understand she used to deliver babies but I felt like this was a ridiculous request. I mentioned how we weren’t really planning to text anyone until after the baby is born, but she was still insistent. So I mentioned possibly taking his phone away if I have to! I’m sorry, but I’m about to push a human out my body for the first time, and he’s my support person. I don’t want him having to stop and text her throughout the process during labor. I feel like it’s a rather selfish request and that people tend to forget that it’s a luxury this technology we have, it does not make us obligated to keep everyone up to date, every second.
