Tips to Choose the Perfect First Birthday Theme

The first birthday for a parent is more than a calendar date, but a celebration of a priceless journey of 365 days. This is a time, as parents, that we feel proud to look back on a wonderful year filled with our child's laughter, innocence and her small accomplishments. Choosing the right theme on such a special day can turn the party into a dreamland.

1. A child's smile is the biggest sign

Choose the theme that brings a sparkle in your child's eyes and a smile on his face. If he claps on seeing balloons, then choose the Balloon Wonderland theme. If he giggles on seeing cartoon characters, then decorate the theme on that.

2. Simplicity is beauty

Remember, theme does not mean expensive decorations, but smart and heartwarming details. More complex decorations do not matter to children, but small cute touches are very pleasing to them.

3. Decorate memories with colors

The color combination determines the mood of the party. Pink-peach, lavender-gold, blue-white or mint-green – such colors will make the party Instagram-perfect and the pictures will also shine.

4. Not just decorations, games are also important

The world of children is incomplete without games. So do not forget to add small games to the theme – like “balloon pop”, “treasure hunt” or “fish catching”. These will be fun for children as well as adults.

5. Create a memory corner

Every theme should have a photo corner. Arrange colorful props and install a backdrop suitable for the theme. Many years from now when you will look at these photos, the same smile that now crosses your little one's face will again appear in yours. 

Keep in mind – the perfect birthday theme is not defined by decoration, but in the way it captures your child's innocent smile, and your sincere memories in the most beautiful form!
