I watched my granddaughter (still do during summer and school holidays) and now watch my grandson. Granddaughter was fine. Grandson is a handful but okay. My provider friend also watches her grandchildren. Hers is a different story and somewhat similar to yours.
Her granddaughters are fine but her grandson is a holy terror. It is a long story but the bottom line is she only watches him part time now. Her two provider friends (me and our other friend) feel she shouldn't watch him at all but sometimes you can't tell her anything.
If I were you I wouldn't watch the older one but would watch the younger one (if you really want to).
Is it possible she is doing you a favor by enrolling the oldest elsewhere? Maybe she realizes it isn't fair of her to expect you to watch the child who has such bad behavior?
It sounds like the two of you need to have a heart to heart talk in person.
