How to put it together

  1. 1

    Dress your baby in the soft cotton bodysuit and leggings as a comfortable, warm base layer.

  2. 2

    Layer the plush pumpkin tabard or fleece romper over the bodysuit, ensuring the armholes are clear and comfortable.

  3. 3

    Secure any snap closures along the bottom diaper area for easy access later.

  4. 4

    Place the soft knit beanie gently on the baby's head, making sure it does not slide down over their eyes.

  5. 5

    Slip on the soft-soled booties or thick socks to keep their feet warm.

  6. 6

    Double-check that there are no loose buttons, scratchy tags, or choking hazards before heading out.

Makeup & hair

Keep your baby's skin completely free of makeup, face paint, and hair products to avoid irritation.

Tips

  • Prioritize diaper access by choosing costumes with snap closures along the inner leg seams.
  • Dress your baby in layers so you can easily adapt to indoor heating or outdoor autumn chill.
  • Take photos early in the day when your baby is well-rested and fed, rather than waiting for evening trick-or-treating.
