My 13yr old granddaughter has been diagnosed by 2 Drs as being bipolar and ADHD. I don't doubt the ADHD but I do question the bipolar. Why? Because she can and does behave very well in church,at school,visiting other people's homes,going somewhere with other people,out to eat,etc.etc. It's only at home and our house that she can be very disruptive,argumentative,complaining,etc. How can she behave so well "out" if she's truly bipolar?? Is this normal????
