The only concern Sirius had was Harry’s nightmares. He may be a child in an adult’s body, but Sirius wasn’t stupid. He could tell Harry wasn’t getting enough sleep. The only thing he could think of to help his godson was Occulmency, but the grim animagus had never been very proficient in that area. (Actually, he’d never been proficient in any of the Mind Magicks. He wasn’t able to sit still for the amount of time required to even begin meditating. The animagus meditation took him forever and a day to accomplish.) So, he raided the Black library for every text he could find on Occulmency to give to Harry.
