Davenport, who clinched her 53rd singles title on the Sony Ericsson WTA Tour at this month's Quebec City Challenge, had one major fear when she returned to the circuit.
"It was the doubt," she said. "Can I still do this? Physically, my body has changed a ton and I have gone through a lot with the birth.
"And how have the other girls changed, have they gotten so much better in the last year? I didn't really know what I was up against.
"But I have a strong will and a good, competitive spirit and I thought it was a great challenge for me to try and come back into shape and start playing well again. The biggest fear was not being good any more."
