Hire a photographer or designate a family member to take photos. Be sure to capture key moments such as the cake smash, family portraits, and candid interactions.

Focus on Meaningful Details

Personalized decorations, milestone photo displays, and memory boards help tell the story of your baby’s first year and make the celebration more meaningful.

Keep Guests Entertained

Simple activities such as coloring stations, bubbles, sensory bins, or themed games can help keep young guests engaged and entertained.
