We were there for like half hour and she told my MIL, myself, and my DH to be quiet and no one was talking O.o and even if we were its not a Childs place to tell an adult to be quiet! she put her little finger directly in all our faces one by one, while telling us to be quiet my DH said something to correct her and she made this flem hacking sound at him, right in his face. My MIL is there for the whole thing and just makes excuses for it the whole time, like ooh she's just playing... I can't imagine what she's like at Home with her parents and I can't believe they put up with it. My SIL is a first grade teacher, supposedly a really good one! Yikes! If she can't control her own offspring I'm beginning to doubt she's even an ok teacher.
How can I keep my own child from picking up such awful habits from her cousin...?
