My sister's parenting drives me insane! My niece (at the age of two) carried a vodka bottle in and said "drink mommy". She and her husband laughed at how much she loved the taste of vodka. Who gives vodka to a 2 year old?!? And she smacked her son's butt once (I don't have a problem with spanking when it is done correctly) because he wouldn't lay still while she changed his diaper. He was four months old.
And most of the time she just drops the kids off with someone else and forgets about them.
