“Me doneee!!”

The 3 laugh, Sirius gives Harry some money, Harry’s little mouth opens and says

“Whatdisdis?”

Sirius chuckles and says,

“Money, Harry.”

Harry does his gummy smiles says

“My moonyy?”

Since Harry can’t pronounce correctly,since he’s only 1, he accidentally said Moony instead of Money. Moony is Remus’s nickname, Sirius playfully gasps and jokingly says,

“Harry, no, Moony is mine, money is yours.”

Remus and Peter laughs while James and Lily tries to clean up Harry’s mess, Harry can’t pronounce words correctly yet, since he’s only 1.
