Padmé was correct to assume Anakin had not changed over the past twenty three years in regards to his need to be constantly doing things. He still didn’t like meditation. He still didn’t like remaining in one position for more than was necessary – he’d only begrudgingly accepted sleep as a necessary activity.
But he had told Padmé whatever she needed of him he would do.
“Yes,” he said, and he even had a measured tone that belied none of his dislike of lying still. He focused more on the plus that Padmé wasn't kicking him out, and that she was at least accepting him for the moment. “However long you want. We’ll work through this.”
