Okay kiddo, when grown-ups decide they want to get married, sometimes they ask someone called a wedding planner to help them. A wedding planner is like a person who helps plan a big party, but this party is really special because it's all about two people getting married.
The wedding planner helps the happy couple decide on things like where the party will happen, what kind of food they'll serve, and what music everyone will dance to. They also help the couple pick out decorations, like pretty flowers and sparkly lights.
The wedding planner also talks to all the important people who will be helping out at the party, like the caterers who make the food and the DJ who plays the music. They make sure everyone knows what they need to do so the party runs smoothly.
On the day of the party, the wedding planner makes sure everything happens on time. They help the couple get ready and make sure all the guests arrive safely. During the party, they make sure everyone is having fun and the bride and groom are happy.
So basically, a wedding planner helps the bride and groom have the best party ever to celebrate their love for each other!
