Cake Table & Highchair Decorations
Make the cake-smash spot special:

Monthly Photo Display
A first-birthday classic: display baby’s monthly photos (months 1 to 12) on a banner, a wreath, a clothesline or a framed grid. It is a sweet way to celebrate how much they have grown in a year.

A simple color palette ties your decorations together:
- Blush and gold for a baby girl
