"We both know it was wrong," he told The Dodo last month. "I'll never make that mistake again. It'll never happen again."
But that hasn't stopped Gainous from receiving a torrent of abuse, and even threats, from around the world. While she regrets what happened, she tells The Dodo, she had no choice but to leave June with her friend.
"I was in an car accident. I was rushed to the hospital and my car was totaled," she says. "And I lost my apartment.
"That's why June was not in my care."
After being sidelined by a shoulder injury, Gainous returned to work - and June was returned to her care.
