But the "Single Ladies" star isn't stopping there. She told ABC in an interview that she would like to have another child.
"I think my daughter needs some company," she said. "I would like more children... I definitely love being big sister," she said of younger sister Solange Knowles.
Through all the appearances, tour stops and recording, baby Blue is still the top priority.
"I feel really, really just lucky that I can still do what I love, and now have a way bigger meaning. And that's to be her mother," she said.
