Hearing Albus speak caused Astoria to stop dead in her tracks, and resulting in her dropping her cookie on the floor.

"Did he just say 'cookie'?" she asked in shock, already knowing the answer.

"Yes. He did," Daphne replied.

Meanwhile, Albus crawled over to the edge of the playpen and stretched his arm out, as though trying to reach for the fallen cookie.

"So, Albus' second word is 'cookie'," Astoria said. "But what was his first word though? Surely, it was 'Mama' or 'Dada', right?"

Harry and Daphne shook their heads.

"Nope. His first word is 'cookie'," Harry told Astoria.
