Make me one?

"Mom?" B asked Simone, glancing up from the book she was reading. "Yes?" "Make me a baby?" "No." Simone returned to her reading. "Mom?" Big sigh. Simone put the book aside. "Yes?" "Make me a baby PUH-LEAZZZZZ?" "No. I am not making you a baby." "Okay," B conceded. "CC can make me one." "She cannot," Simone retorted, mildly horrified. B's 14 year old sister hadn't even started Grade 9 yet! "She's too young." B held up a palm. "Okay, okay. So how old do you have to be to have a baby?" "You have to be at least 18 or 19." B looked up for a moment and, his lips thinning, "Okay. I'll wait three or four years and THEN CC can make me a baby." He paused for a moment then his face lit up. "Wait! How old is M.?" Ugh. THAT sister happens to be 18 years old...
