Brother Not From Another Mother

(I’m the second oldest of seven kids on my moms side of the family, the fourth of ten all together. I’m visiting my mom at her house.)

3-year-old brother: “My mom says—”

Me: “She’s my mom, too.”

3-year-old brother: “No.”

Me: “Yes. She is she is your mom, and my mom.”

3-year-old brother: “No, she’s my mom!”

Me: “She’s your mom and my mom. We are brother and sister.”

3-year-old brother: *runs off while screaming* “Mommy! She says that you are her mom too!”

Mom: “I am her mom, sweetie.”

3-year-old brother: “No, no, no! You are my mommy, and [5-year-old sister’s] mommy, and [10-year-old step sister’s] mommy, and [15-year-old step sister’s] mommy, and [17-year-old step brother’s] mommy, and [21-year-old brother’s name] mommy!”

Me: “What about me?”

3-year-old brother: “No. You don’t get my mommy. She’s mine.”
