A baby’s first birthday party invitation should pique the interest of your prospective guests but remain creative and fun at the same time. You can write out the invitation in the style of a childlike poem or story and point out the sweet details of his progress like first steps or first teeth. You can even make the words into a simple rhyme, so it’s pleasing to read. You can use humor and the promise of what the party will offer to interest guests even more, which will guarantee their attendance on the big day (source).
