In her 12-minute video on Tuesday, Mercado insisted that her son has always been healthy.

“When he was with us, he never had a cold. He never had a fever. He never had a runny nose,” she said. “I was just a mother who needed assistance with something that is very common amongst mothers, and what has been done to my family is unacceptable. It’s sickening.”

“All of this has been a nightmare, and we are still living in a nightmare,” she explained, “because, right now, we are seeing for the past seven months how much our son has been through. We see it in his eyes. We see it in the way he plays. We see it in the way he tries to rest at night.”

While Mercado is pleased that her son is finally home, the singer said that she and her family are “still living this nightmare with the state monitoring us.”

“Know that this is not over,” she told viewers. “A victory to us is being out of the system, to be able to live happy, healthy and free … to not be discriminated against because we choose to live a holistic lifestyle.”

“This is what life is right now, but I’m just gonna focus on my son [and] continue to instill that positivity within him,” Mercado added.

Louis Baptiste, one of Mercado’s attorneys, previously said in a press conference that the children were placed in the care of an estranged relative.

“They’re not where they belong, and they’re not with the person that the parents would choose, and their setting is not a setting which the parents would choose,” he said.
