When Do Babies Start Cooing? All About Your Baby’s First Sounds

One of the most cherished moments of parenting is hearing your baby’s first sounds! You don’t have to wait long, as even newborns make adorable noises. But when do babies start cooing and making other sounds? Read on to learn all about when this special milestone is likely to occur and how to support your baby’s language development.

What Is Cooing?

Cooing refers to single-vowel sounds, such as “ooh” and “aah.” Sometimes the noise your baby makes sounds like the word “coo,” which is where the action gets its name. A cooing baby is making their first attempt at expressive language, which is why this is such an exciting development milestone for your little one! Though you’ll likely hear other baby noises before cooing starts, common crying and grunting are sounds that originate from the chest. Cooing comes from the larynx, the organ in the neck that contains the vocal cords, and involves different mouth muscles than crying does. Cooing is obviously adorable, but why do babies make noises like this? Baby cooing is a way for children to express happiness and contentment before speaking. Your little one might also coo for self-entertainment or to get your attention.

When Do Babies Start Cooing?

Baby cooing may start when your little one is around 2 months. But every child is different and develops at their own pace, so your baby might start to coo earlier or later than other children, and that’s OK. Like every other language milestone, baby cooing takes time to develop. By about 1 month, your baby might be able to identify you by your voice, even if you're not in the same room. When you speak to your little one, they may begin to smile and gurgle at you; your delighted reaction helps teach them the concept of a two-way "conversation." Creating new sounds such as cooing is the next step for your baby. Before long, they'll be using their tongue and lips to create even more precise sounds. Your little one has already come a long way in terms of language development and communication, but the adventure has just begun!

Baby Noises: From Grunting to Talking

After “when do babies start cooing?” comes the question “when do babies start talking?” Your little one is rapidly developing language and communication skills, and it might help to understand what they’re experiencing. So, when do babies start making sounds, and how does a baby go from gurgling to cooing to speaking? Here’s a brief timeline of what many refer to as “baby talk”: 1. Grunting, gurgling, and crying. Your baby’s spoken language development involves these initial newborn sounds. Even within your infant’s first few days, you’ll likely hear a mix of crying, grunting, squeaking, sighing, sneezing, and hiccupping, among other cute noises. As mentioned above, these natural sounds come from your baby’s chest.

2. Cooing. The next step is cooing, which means that your baby will use some different muscles than they did with crying and grunting. Language development typically mirrors fine motor skill development in that it originates from the center and progresses outward, with fine-tuning along the way. Baby sounds begin within the chest, eventually moving to the larynx, tongue, and lips.

3. Babbling. While cooing involves single-vowel sounds, babbling is when your baby starts to include consonant sounds. Those “oohs” and “aah” become “muh-muh” and “bah-bah.” Though these new sounds might seem random at first, when you listen closely you may notice some patterns and rhythms or hear your baby raise and lower their voice. This milestone is common at around 4 months.

4. Talking. Babies don’t typically say their first recognizable words until they are at least 1 year or older. Most likely, the first word will be a simple one with consonants and vowels that they’ve heard repeatedly, such as “mama,” “dada,” or “bye-bye.” Before saying specific words, babies might understand them—in fact, babies understand more than we think! You might spot your little one reacting when you say “no” or “bottle” or when or when you use the signs for these common words if you've chosen to introduce baby sign language to them.

How to Encourage Baby Cooing and Support Language Development

Baby cooing is an exciting and endearing language development milestone, and you might be wondering how to support and encourage your little one's progress. Here are a few things you can do to encourage those sweet baby cooing sounds:

• Talk to your baby. It may seem obvious, but talking to your baby right from birth is one of the best ways to encourage cooing and promote language skills. Before your little one can start cooing and babbling, they’ll listen to you, which is a key part of the process. Through listening, they’ll develop language and social skills such as turn-taking, imitation, pacing and speed, and vocal tone. And once your little one starts to coo, repeating those sounds as you respond will encourage them to keep going!

• Phase out baby talk when the time is right. It’s easy to get stuck in baby talk, meaning imitating your little one’s noises and using only a high-pitched voice. Once your baby starts cooing, mix up your conversations with language and tone suitable for older kids, slowly phasing out those “goo-goos” and “gah-gahs.” Of course, as mentioned above, repeat those coos, but just remember to include other words and tones.

• Describe objects and situations. Remember that your baby is always listening and will understand words before being able to say them. You can help foster language development by describing what’s around your little one or what’s happening in each situation. For example, tell your baby what they’re wearing (“Here's your red sweater”) or what you’re doing after a bath (“Let's dry you off with a big, soft, towel”).

• Use consistent language. When you mention or describe familiar objects, try to stay consistent with labels to support your baby’s development. For example, if you have a dog, stick to that word rather than mixing in “doggy” or “puppy.”

• Ask questions. Even though your child can’t yet answer you, asking questions and providing answers yourself will help build vocabulary and enhance language comprehension. Repetition is a crucial step in language development, so asking “What’s this?” and answering “It’s a tree” each time you’re on a walk will help support these important skills.

• Read with picture books. A terrific way to build new vocabulary into your baby’s everyday life (and practice with repetition) is to look at picture books together. Plus, reading to babies can spark an interest in books as they get older!

Baby Not Cooing: What Does It Mean?

If you’ve passed the 2-month mark and your baby is not cooing, there isn’t necessarily any reason to worry. As mentioned above, children develop at their own pace, and some reach these typical milestones later than others. Contact your child's healthcare provider if you have any questions or concerns. Instead of focusing on cooing alone, pay attention to your baby’s range of sounds. Call your child’s healthcare provider if your baby isn’t producing various sounds by 6 months, or if they’re not babbling or imitating sounds by 7 months.

The Bottom Line

Baby cooing is just one step in your little one’s long language journey. But it’s certainly an important achievement, as it’s your baby’s first attempt at expressive language. Feel free to celebrate and enjoy this milestone, knowing there’s much more to come! In anticipation of this memorable achievement, you might ask, “When do babies start cooing?” and want an exact answer. Remember that babies develop at their own pace, so not every child will start cooing at the same age. Typically, babies start making cooing sounds around 2 months old, but it can occur earlier or later. The best way to encourage and support your child’s cooing and language journey is to talk to them from birth. Babies learn to talk before they can actually speak by listening to you! You can also read picture books, describe situations, and use consistent language.

Remember that your little one is on their own path, and cooing, babbling, and talking will all come in time. Contact your child's healthcare provider if you have any questions or concerns. “Diaper” might be a frequently used vocabulary word at the moment!
