The newest addition to the family of Dr. Jennifer Arnold and Bill Klein of TLC’s hit reality show The Little Couple is ready for her close-up.
“She is a very strong personality,” says Arnold with a laugh. “She is a happy girl.”
The past four months have been challenging, to say the least, for Arnold, 39, a neonatologist at Texas Children’s Hospital and Bill Klein, 39, a business owner who runs their Houston-based pet store Rocky & Maggie’s Petshop.
While in India picking up newly adopted daughter Zoey, 2, from an orphanage, Arnold experienced severe bleeding and had to return home to Houston for treatment. She went through months of weekly intensive chemotherapy treatment to battle a rare form of cancer and now is in remission.
The trying months of settling Zoey into her new family, along with their son Will, 3, are finally behind them.
“Zoey loves riding on cars and Will loves pushing her around,” says Arnold. “It is the cutest thing ever.”
