Not a parent but a big sister to an 8yo, I'm about ten years her senior.
Mom has left for a month (caring for her parents) and with dad working it's up to me to make sure my sister is doing ok. Every morning I try to get her ready (teeth brushed, hair combed, etc), but every morning she refuses to listen to me and decides to go play or do literally anything else than what I ask her. I'm not proud of the methods I use to try and get her to work with me, such as threatening to tell dad or promising to spend extra time with her. Most of the time I end up having to get dad involved, and then finally she listens to HIM (doing it as reluctantly as possible, of course).
I'm just really frustrated and looking for advice as to how I can get her to listen to me so we don't have these battles every day. I know I'm not the best big sister especially if she respects me so little, but I'm really trying to help her into a solid morning routine and good habits. Also as a side note, she's homeschooled and so never really had to do the whole getting-ready-before-leaving thing. Often she pushes back brushing her teeth to later in the day or just never gets dressed or does her hair at all.
Please help. Any advice at all is much appreciated.
