You and Alhaitham lived together, which made it easier for Alhaitham to regress and indulge in his own little world in his head. You never minded it. He was always content playing by himself.

You had been in the kitchen making the two of you some lunch when you heard a loud thud. Quickly rushing to the source of the noise you found Alhaitham on the ground, holding his knee a bit as he teared up. He had tripped over a box full of books while wandering around.

Alhaitham looked up at you tearfully, whining slightly as he held his leg close to his chest. He likely had a bruise on his knee from the fall.
