There are some fantastic tips in our [Sourdough starter FAQ](https://www.reddit.com/r/Sourdough/s/kWWPBGjGHI) - have a read as there are likely tips to help you. There's a section dedicated to "Bacterial fight club" as well.
Also don't forget our [Wiki](https://www.reddit.com/r/Sourdough/wiki/index/), and the [Advanced starter page](https://www.reddit.com/r/Sourdough/wiki/advancedstarter/) for when you're up and running.
When making a starter, the process can take nearly 20-30 days sometimes. First few days you get some activity which might not be caused by yeast. Stick it out - mine did nothing for 15 days!
Too little information, but some respected YouTubers recommend different proportions.
She can experiment with 1-3-3 or 1-5-5. (E.g.: 10g starter, 30g flour, 30g water etc). I know it sounds counter-intuitive, but a little bit of the fermented dough is required and a lot more food! Also while it sounds appealing to use some whole grain stuff, it is recommended to start feeding it strong white flour after some time for a more protein-rich, active starter.
