It wasn't a very happy birthday for Bobbi Kristina Brown on Sunday. The only child of the late Whitney Houston and Bobby Brown turned 19 March 4 -- just two weeks after the shocking death of her pop singer mom at age 48.

At her mom's side in L.A. during her final days, the young woman was rushed to the hospital hours after her mother's lifeless body was discovered in the bathtub at the Beverly Hilton Hotel Feb. 11. And on the day of an emotional three-and-a-half hour funeral service for her mom Feb. 19 in Newark, NJ, Bobbi, who idolized her Grammy-winning mom, went missing.

"Bobby is now with the family and going through the grieving process just with them," a source explained to Us Weekly.

Another family insider adds that she and her maternal grandmother, gospel singer Cissy Houston, "have been getting along a bit better."

Explains the second insider: "She really needs her own space right now to heal, and Cissy knows that."
