Like Raspberries? How Blowing Bubbles and Razzies Helps Your Child Develop Invaluable Communication and Social Skills

The first time it happens, you don’t expect it. Your baby looks at you, sticks out their tongue and makes a gentle razzing sound. It’s almost impossible not to smile and make a raspberry back at them. Just try.

What starts as a fun and silly game between parent and baby actually sets the foundation for language, social skills and fine motor skills, such as eating and drinking from a cup. So pucker up those lips and help your baby begin to experience a whole new world.

Raspberries – More Than Just a Fruit, They’re a Workout

Most babies start blowing raspberries and bubbles between six to eight months of age. After a few tries, they usually catch on quickly, particularly if you encourage them. And you should blow back; besides being darling, those raspberries teach a variety of important skills.
“Razzies really teach babies how to regulate their voice, how to turn it on and off, change the volume and the pitch. It shows them how to navigate the diaphragm, mouth, lips and tongue,” explains Tara Kehoe, a speech and language pathologist at Easter Seals.

All that noise gives the jaw a great workout by exercising the muscles needed to move lips independently of the jaw and tongue. That’s a crucial skill for when they start using a spoon and eating chunkier foods.

Speech and Language Pathologist Mary Barry explains, “Lip raspberries are just lip and no tongue. They help develop lip tension so that when babies start drinking and eating, they will have the appropriate tension to provide a seal for skills such as cup drinking.” Think of it as a workout for lips.

Have Fun With this Stage

But what parents notice most about the raspberry stage is that it’s just plain fun. Babies laugh and giggle in response to their parents lip-blowing and then they do it back. It’s the early foundation for the back and forth rhythm of a conversation.

Frequently, this is when older siblings begin to realize that the baby is capable of interaction. “My then three and five year olds had a great time at this stage. They would be smiling and laughing and just go back and forth. It was really a great bonding time,” says Carrie Raeside, a mother of five.

Blowing raspberries is almost nature’s way of ensuring that you join in. “We usually just do it automatically, it’s so cute,” says Kehoe. Try to imitate your child and then wait for their reaction. “Use lots of non-verbal communication - eye contact and expression,” encourages Barry. “Show them how enjoyable it is. Show them how to manipulate their environment by making sound, that’s really what language is. Just match the sound, wait and go back and forth. Balance and match.”

New Sounds, New World

Once they’ve mastered the raspberries, be ready for language to start developing. Courtney Romano, mother of a seven-month-old, states, “I think blowing the bubbles has taught her how to use her mouth and enhance her language skills. Right after blowing bubbles, she started using different sounds like her ‘G’s’ and ‘B’s’ in her baby talk.”

Early speech usually entails repeated consonants and vowels with no discernable meaning. Much to the delight of mom and dad, the “m,” “d,” and “a” sounds are frequently the earliest. Hence, “mama” and “dada” are often two of the earliest words. That soon develops into long strings of words such as “bababababa” and then eventually combined consonants for nonsense words, such as “takomamano.” They frequently combine gesture with the sound so you might get “ah” with the arms raised for “up.”

Reason for Concern

Talk to your doctor if your baby isn’t making any vocalization by eight months. Some babies may skip the raspberry stage but they should make some type of sound that plays with their lips and their mouth. If not, it could be an indication of delayed speech development or a hearing issue.

Otherwise, enjoy those raspberries and bubbles. Play other games of cause and effect with your baby and get them to communicate back to you. It’s an amazing and wonderful time of life, enjoy every sweet smile and laugh!

Keep Those Funny Games Going

Blowing raspberries is only one of the many silly yet educational games you can play that work on language and social skills.


  • Try imitating whatever sounds your child makes. Go back and forth and have a ‘conversation.’ Once in a while, add a new sound, then wait and see if they imitate. For instance, if they’re already saying, “Dada,” try getting them to say, “Gaga.”
  • Play with sound by changing the pitch of words when you talk or sing to them. For instance: high/low, fast/slow, soft/loud.
  • Gently rub your fingers on baby’s lips and try to get them to make a rolling sound.
  • Put your lips on their body (stomach or arms) and gently blow.
  • Sing familiar songs using different voice sounds: a low growly voice, a high squeaky voice, a soft whisper. Or grab a stuffed animal or puppet to help you sing.
  • Encourage your baby to ‘talk’ into a play telephone.
  • Babies love combining action and words so try a variety of finger songs. Some tried-and-true favorites include Itsy-Bitsy Spider; Wheels on the Bus; and Row, Row, Row Your Boat.
  • Above all, talk, talk, talk to your baby. There is no greater gift for encouraging communication and social interaction than simply talking and engaging them with your voice.
