Juvenile With a Baby In-Jail

Hello,
My juvenile dependent was locked-up all year until 12/15/10. While in jail, she turned 18 in June. She also had a baby girl in July. They both now live with us again while she tries to get her life together. My questions are: A) Can I still claim my juvenile as a dependent for 2010? B) Can I claim my granddaughter that was born in July as a dependent for 2010?
thank you,
Andrew Willi
