A baby cooing is perhaps the most pleasant sound for a parent. While babies announce their entry into the world through crying, cooing is their first language and communication cue. It is one of the first crucial milestones they develop in their first year. No wonder it is no less than soothing music for parents.

In this post, we help you explore more about baby cooing. We have also included information on its benefits, ways to encourage, and of course, when you can expect your baby to coo.

What Is Cooing?

Cooing is the spontaneous behavior of an infant to communicate their needs and feelings.

Cooing usually refers to the vowel sounds that babies produce. These sounds could include monosyllables, such as “ah,” “ooo,” or “eee,” and disyllables, such as “ah-ah,” or “ooh-ooh.”

When Do Babies Start Cooing?

Generally, a baby starts to coo or make gurgling sounds when they are about two months old (1). At this age, they also start responding to sounds, smiling, and mimicking your facial expressions (1) (2).

As is true in all milestones, some babies may take more time to start cooing, as all babies develop at their own pace. However, if your baby does not coo by three months, consult your baby’s pediatrician.

Do remember
After cooing for about three months, your infant will start babbling and producing strange sounds to amuse themselves.

How Does Cooing Help Babies?

Here are a few ways in which cooing helps babies(1) (3).

  1. Skill development: If your baby starts cooing, it means your baby is developing communication skills. It is your baby’s attempt at vocalizing their needs. As time pass, they will begin to understand more complex sounds.
  1. Mouth exercise: Cooing involves different parts of the mouth. A baby starts exercising their lips, palate, and tongue as well as jaw with their constant cooing and gurgling.
  1. Bonding:

    It helps create a special bond between you and your child. When you make certain sounds and gestures, they start acknowledging them and try to mimic them.

  1. Understanding needs: Cooing is your infant’s means of expression. Through this, they try to communicate their pain, happiness, hunger, etc. It will give you first hand experience of your baby’s reactions and help you read your baby’s cues better.
  1. Language development: The first language of a child, besides crying, is cooing. Cooing offers your infant vocal practice and prepares them to learn a language.

How To Encourage Babies To Start Cooing?

It is absolutely divine to see a baby react to your “coochi coos” with their coos or with a smile. Here’s how you can encourage them to coo and use their pre-language development skills such as facial expressions, imitation, gestures, and eye-contact (1) (2) (3) (4) (5).

1. Communicate with your baby

Communication is crucial for any language development. Speak to your child as it will encourage them to respond to your gestures. You can engage them by showing them a toy and describing it. Repetitive use of common words in your everyday conversation can help your child associate words with objects.

2. Keep speaking frequently

Babies understand words long before they begin to speak. Speak to them in the language you speak. Babies love to imitate. If you show excitement, they will respond to you in the same way. Keep speaking whether you are feeding them or taking them out for strolls. Touch your nose, lips, and eyes and encourage them to imitate you.

3. Tell them what you are doing

If you are giving a bath to your child, show them their tub before putting them in it. Tell them how you form bubbles from the shampoo. If you are working in a kitchen, show them different vegetables and fruits. When you take them out in a car, let them peep out of the window, and talk to them about the different vehicles moving by. These will help in developing their cognitive skills, which are crucial for early language development.

4. Use actual words

Use actual words while talking to your baby. Say “orange” instead of “olange”. Speaking to your baby using “baby talk” is not encouraged, because the child loves to imitate you. Wrong words will send the wrong signal to the child. It’s okay to blabber with them once in a while, though.

You might think it’s early to introduce them to words, but you’re helping them learn their first words. When they say their first words, which generally happens at around six months, you would want to hear real words, such as “mama” or “dada.”

Quick tip
Help your baby form new sounds by letting them mouth safe objects like baby toothbrushes and kitchen spoons. It helps in speech development.

5. Maintain eye contact

Always maintain eye contact with your baby to attract their attention. Babies start paying attention to objects and faces and recognizing people at a distance at around two months. Eye contact is a non-verbal form of communication that can help them build focus. It can also help them differentiate between you and a stranger.

6. Repeat your child’s sounds

Whatever sound your child makes, try to repeat it. Always react enthusiastically to your baby’s sounds. Enjoy this two-way conversation. This will let your baby know that you are there to fulfill their needs.

Point to consider
Sit facing your baby and make new sounds. If they make a different sound, repeat it and add another sound.

7. Sing to your baby

We all have slept to the lullabies sung to us by our parents or grandparents. Do the same with your baby. See your baby’s response when you sing to them. They might start cooing along with you and gradually go into a deep slumber. Interestingly, music also encourages cooing in a baby.

A study conducted by scientists at the University of Washington’s Institute for Learning & Brain Sciences (I-LABS) has shown that music helps improve infants’ cognitive skills and the ability to detect patterns in sounds.

8. Read them a story

It is never too early to acquaint your child with books. Read out stories to your child by emoting with expressions. Reading gives your baby an opportunity to hear new sounds. Colorful pictorial images of the storybook can excite them, too. While reading a story, emphasize the simple words, such as love, happy, and sad, to elicit your child’s reaction.

9. Explore the world with your baby

It’s always fun to take your baby outdoors to familiarize them with birds, animals, and many other things nature has to offer. This is another way of developing their language skills. Every new thing that excites them will encourage them to coo. Take them to a garden and look at their reaction when they see a bird flying. It’s always a good idea to keep talking to your baby while exploring any place to boost their cognitive skills.

Frequently Asked Questions

1. What comes first, cooing or babbling?

Babies begin to coo by the time they are two months old and babble by four months. (6)

2. What’s the difference between cooing and babbling?

Cooing is when the baby makes single-syllable, vowel-like sounds, such as ah-ah-ah, ooh-ooh-ooh (6), and babbling is when they pronounce a syllable by combining a vowel with a consonant; example: da ba. (7)

The sound of a baby cooing is one of the most lovely sounds that parents and caregivers adore, and it also serves as a means of communication. For about two months, infants make vowel sounds to communicate with those around them. Cooing is a useful mouth exercise for babies and also the beginning of vocalization. This may also help them form stronger ties with their loved ones and communicate their needs. To encourage your infant to speak, establish eye contact and talk to them constantly.
