Writing a 1st birthday card can be a special way to celebrate a childs first year of life. Here are some ideas for what to write in a 1st birthday card:

• "Happy first birthday! You may not remember this one, but we’ll be here for all of the birthdays to come to remind you just how much you are loved."
• "Never forget how much we love you."
• "We can’t believe you’re one already, we’re so excited to watch you grow."
• "Happy first year on Earth, little one!"
• "You won’t remember this joy-filled birthday, but we always will."
• "It was your first trip around the sun, and I sure hope that it was fun."
• "Watching you grow is the greatest privilege."
• "You have completely stolen our hearts and there is nothing I wouldn’t do for you."
• "It’s been a year of joy, love and laughs with you. Excited for all the new adventures to come. Happy first birthday!"

Remember to keep the tone light and celebratory, and to express your love and excitement for the childs future.
