"I told her, you need to tell Sean I was a good father and I will be a good father. You have to do it for him," Goldman said. She complied, he said.
ABC News spoke today with the Brazilian matriarch, Silva Bianchi, who said: "I am very, very sad. My country didn't protect us, protect Sean."
Bianchi said she spoke to Sean today and the conversation reassured her that the boy was all right.
"I am more comfortable now because he's OK with his dad. He told me it's cold, he's sitting by the fireplace and he's playing. I think he's doing OK there and that makes me feel better," she said.
Between tears, Bianchi said it was hard on the rest of the family, particularly Sean's younger sister.
"His sister misses him a lot. She calls for him all day, walks by his room asking for him, looking for him. It's so upsetting," she said.
Goldman said his son would be allowed to see his Brazilian family members "in the appropriate time and under appropriate conditions."
He said the families need to come to a settlement, "something collectively. It can't be this constant battle."
