Celebrate Your Baby’s Birthday—With Signs!

Your baby’s birthday is more than a milestone—it’s a celebration of everything they’ve learned, discovered, and become in their first year (or two, or three!). And what better way to mark the occasion than by using signs your baby already understands and loves?

Whether it’s their first “cake” or the thrill of a big balloon, using signs during your child’s birthday celebration helps them feel included, understood, and part of the excitement—even if they’re not speaking yet.

🎂 Birthday Signs to Know and Use

These Baby Signs® are perfect for birthday parties and everyday celebrations:

🎈 Balloon – Babies are mesmerized by balloons! Signing “balloon” helps them point it out again and again.

🎂 Cake – Babies love birthday treats! Signing “cake” builds vocabulary around a sweet moment.

🕯️ Candle – Signing “candle” before blowing it out helps babies anticipate the fun.

🎶 Song/music – Signing “song” while singing Happy Birthday shows babies how to join in the celebration.

😀 Happy – Reinforce the joyful emotions of the day by signing “happy” as you talk about the celebration.

🍦 Ice Cream – If your celebration includes a sweet, chilly treat, don’t forget this fun and motivating sign!

You can also use everyday signs like “more,” “eat,” “all done,” “thank you,” and “help” to support your child’s needs and reduce frustration during a busy event.

  • At the cake table: Sign “cake,” “candle,” “more,” and “eat” to build connections during their favorite part of the day.

  • With gifts: Show the sign for “gift” or “thank you” while helping your baby open gifts and engage with loved ones.
