The 32-year-old singer, who is married to Swiss Beatz said even though her son is so young he swims by himself, reported Daily telegraph.
"Sometimes he doesn't like cameras. But I think he's got into it," Keys said.
"He swims by himself, he is so independent, he is extremely smart. I ask him to count to tens from 500 to 100 and he can do it. His rhythm is kind of impressive!," she added.
Keys said she may have another baby in future but the couple are not thinking about it presently.
