Why We Sing Everything: The Hidden Benefits of Music for Toddlers

If you walk into Sunny Child Care in San Jose at any given moment, chances are you will hear singing. We sing when we wash hands. We sing when we clean up. We sing when we sit down for lunch.

You might think, "Wow, these teachers really love musicals." But actually, there is a scientific reason behind our constant serenading. Music is a cheat code for the toddler brain.

Here is why we sing everything, and how you can use this trick at home to make your days smoother.

1. Music Greases the Wheels of Transition

Toddlers hate stopping one activity to start another. Transitions are the #1 cause of tantrums.

• The Science: Spoken instructions ("Clean up your toys") sound like demands. Sung instructions ("Clean up, clean up, everybody everywhere...") sound like a game.
• The Strategy: Don't say "Go take a bath." Sing a "Bath Time Song" (make up any tune!). The melody signals the brain to switch gears without triggering the "fight or flight" response.

2. It's a Memory Super-Glue

How did you learn the alphabet? You sang it.

• The Benefit: Music engages multiple parts of the brain at once. Information attached to a melody is stored in long-term memory much faster than spoken words.
• Bilingual Bonus: This is especially true for learning Chinese. Tones are easier to mimic in song. If you want your child to learn Mandarin, play Chinese nursery rhymes in the car. They will be singing along before they can speak full sentences.

3. It Regulates Emotions (Co-Regulation)

Have you ever seen a crying baby calm down when a mother hums?

• The Science: Rhythm mimics the heartbeat they heard in the womb. A slow, low-pitched song (like a lullaby) physically slows down their heart rate and breathing.
• The Strategy: When your toddler is melting down, try singing a slow, familiar song instead of talking. It cuts through the noise and helps them find their center.

4. You Don't Have to Be Beyoncé

Parents often tell me, "But I can't carry a tune!" Your toddler does not care. To them, your voice is the most comforting sound in the world.

• Tip: You don't need complex songs. Just narrate your life to a simple tune (like Twinkle Twinkle Little Star).
  • "Now we put our shoes on, shoes on, shoes on..."
  • "We are eating broccoli, yum yum yum..."

So next time you need your toddler to do something, don't yell it—sing it!
