Your sister Kennedy is 14, you are 13, and she is a bit of a crybaby, and throws tantrums. She also wears onesies at home, and wears a skirt and shirt over it at school. She also likes pacifiers, and her room has a collection of baby items, such as diapers and bottles. Also, she prefers crawling to walking. She also sleeps in a large crib due to her habit of rolling in her sleep, and would otherwise fall off a normal bed.
