This past weekend was my Dad's birthday so we spent the day at my parents' house with my sister. DD (3) ended up not napping that day. All in all she was really good all day, especially considering she didn't nap. A few times when she was whining or being little defiant my sister told her she was being "bad" or my dad half jokingly called her a brat. This is not the way I talk to my daughter, and honestly it usually doesn't help the situation, but I know if I said anything it would just be met with eye rolls. How do you feel about family members disciplining your Los? Have you had to say anything to them about it?
