Planning tips

• Keep it baby-friendly: short party (1–2 hours), shade and comfy feeding/changing areas, and simple décor at baby height for photos.
• Choose one or two standout elements (balloon arch or dessert table) rather than over-decorating.
• Create a photo zone with a backdrop and a few props for easy memories.

Quick checklist

• Invitations: Clear time, location, parking, and any special requests (snack allergies, sibling attendance).
• Food: Keep it simple—finger foods for adults and soft, baby-friendly options for little ones.
• Safety: Anchor décor securely, keep small objects out of reach, and have a quiet space for naps or feedings.
• Keepsakes: Guest-book with wishes, a handprint station, or a time capsule with small notes/photos.
