Apparently this is a one-sided deal. Poor Bella does not get to call dibs on her own things:

I ran across these toddler sharing rules:
1. If I like it, it's mine.
2. If it's in my hand, it's mine.
3. If I can take it from you, it's mine.
4. If I had it a while ago, it's still mine.
5. If it's mine, it must never appear to be yours in any way.
6. If I'm doing or building something, all the pieces are mine.
7. If if looks like mine, it is mine.
8. If I see it first, it's mine.
9. If you are playing with something and you put it down, it automatically becomes mine.
10. If it's broken, it's yours.
Pretty accurate around our house these days!
