How to Order

  1. Select the Big Cousin message in blue from the dropdown.
  2. Select your garment and size from the available dropdown options.
  3. Enter the complete date wording in the personalisation box, for example 'Est Jan 2027' or 'in January 2027'. Replace the sample date with your own and include only the prefix you want printed.
  4. Enter only the wording you want printed. Contact us before ordering if you want to change another part of the design or its layout.
  5. Check your selections, spelling and any date, then add to basket.

For a pregnancy announcement: Our newborn baby vest is the most popular choice.

For a more premium feel: Choose a baby grow with integrated feet for a complete outfit and a keepsake of your announcement.

For a budget-friendly option: Our one-size bib offers the same personalised design at a lower price.

Baby vests are available from newborn to 12-18 months, and baby grows from newborn to 6-12 months. If you would like your baby to wear the outfit later, choose the size for when you expect to use it. Check our size guide for measurements before ordering.

We understand that some moments are meant to be shared on your terms. Whether you’re planning a surprise announcement or keeping your news private a little longer, your order is handled with complete discretion from start to finish.

All items are shipped in plain, unbranded packaging, with no indication of the contents inside.

Your special moment stays yours until you’re ready to share it.

Q: Can I leave off the date beneath Big Cousin?

A: Contact us before ordering to confirm that the date line can be omitted. Do not enter 'no date line' as wording to print.

Q: Can I return a personalised item?

A: Personalised items can't be returned unless faulty or we've made a mistake. If there's a problem, contact us and we'll put it right.

Q: How should I wash the garment?

A: Wash at 30°C inside out. Do not bleach. Tumble dry on low and iron on the reverse, avoiding the print.

Q: Will the print last through washing?

A: We print directly onto the garment with ink designed to stay vibrant through repeated gentle washes. Follow the care instructions to help protect the print.

One little vest. So many beautiful surprises.

Share your biggest little secret in the sweetest way. From your partner to your loved ones, make the moment unforgettable.
