You can do a search on off topic posts by me and you will see that the MIL thinks she OWNS my youngest.
Aunt C came because she has a niece who is there a lot and that's what she calls her and my son was 3 when DH and I got married, heard the niece call her that and started calling her that as well. She decided she was ok with that.
I'm telling ya'll, this lady is NUTS.
We were there the other day (she asked to see dd5) and I went to fix dd5 some soup. Well, you know how sometimes the soup can separate? The MIL saw that and FLIPPED OUT! She told DH I was about to feed dd5 POISON!

I swear she called half the family telling them she was worried about the safety of dd5 because I almost fed her poison soup.
