Big Sister Jumper | Personalised Ballerina Mouse Big Sister or Big Cousin Sweatshirt, Pregnancy Announcement

A big sister jumper that breaks the news for you. Each sweatshirt reads "I may be little, but I'm going to be a Big Sister" or "Big Cousin", finished with your own month and year, with watercolour ballerina mice in peach and sage tutus. White or light pink, kids 1-2 to 12-13 years, and sold individually so sisters and cousins can each have their own.

THE DESIGN

Choose three ballerina mice in peach and sage tutus dancing above the wording, or one ballerina mouse holding a star wand beside it. The wording "I may be little, but I'm going to be a Big Sister" (or "Big Cousin") is printed in soft grey script with your month and year beneath, for example "EST NOV 2026". Printed in soft peach, sage and grey on a white or light pink sweatshirt.

FREQUENTLY ASKED QUESTIONS

Is it sold as a pair?
No, each sweatshirt is sold individually. For sisters or cousins, add each size to your basket with its own design choice and date.

Can I have Big Brother instead?
Our Big Brother design (the retro Cool Big Bro Club) is a separate listing in sweatshirt and T-shirt.

Is there a T-shirt or baby grow in this design?
Yes. The same ballerina mouse Big Sister and Big Cousin design is listed separately as a kids T-shirt, baby grow and baby vest, so a toddler can match an older sister.
