29yo Grandma? I am not surprised>

It's your word against hers, and, as I said in another post, Child Welfare will tend to accept her word over yours.

There was a huge story a few years ago when I lived in California (well, I guess a dozen years ago now). A woman and her Mother were arrested and put in jail for prostituting a pair of sisters. The whole area was in an uproar over how this Mother and Grandmother could do this to these two poor children. The women stayed in jail for almost a year (or maybe even a little longer than a year) waiting on their trial. Finally it was discovered that the girls made up the whole story to get back at Mom and Grandma for not letting them go to a party.

When it comes down to it, CWS doesn't have a whole lot of choices. The option of believing you or your daughter, they would have to believe her first and foremost, as that would be the most dangerous to be wrong on.

It's not a matter of knowing how to be a parent. It's a matter of being in control of your child, and you no longer have a choice. If the child wants to take control, they can with the state's (implied) blessing.
