Babies start experimenting with blowing air around 6 months old, when most begin blowing raspberries by sticking out their tongue and pushing air through their lips. But the ability to blow air with real control and direction doesn’t arrive until closer to age 2, and it continues maturing through age 3 or 4.
The First Stage: Raspberries at 6 Months
Blowing raspberries is one of the CDC’s listed milestones for 6-month-olds. At this stage, babies aren’t deliberately controlling airflow. They’re discovering what their mouth can do, experimenting with their tongue, lips, and breath all at once. The result is spit bubbles, vibrating lips, and a lot of drool. It looks messy, but it’s meaningful. These early experiments build strength in the lips and cheeks, the same muscles that will later support speech, eating, and intentional blowing.
Controlled Blowing Arrives Around Age 2
There’s a big gap between blowing raspberries and blowing out a candle. The average child cannot blow out the candle on their first birthday cake. By their second birthday, most children can be taught to do it, and by their third birthday, blowing out candles is no longer a challenge. This pattern suggests that controlled, directed airflow develops around age 2 and matures by age 3.
What changes between 1 and 2 is the ability to round the lips tightly, coordinate a burst of exhaled air, and aim it in a specific direction. These are oral motor skills that require strength in the lip and cheek muscles, plus enough cognitive development to understand the goal (“blow the candle out”) and translate that into a physical action.
Bubble Wands Take Even Longer
Blowing through a bubble wand is surprisingly difficult for young children. It requires a very specific airflow: steady, gentle, and sustained. Blow too hard and the bubble pops before it forms. Blow too soft and nothing happens. Georgia’s early learning standards place bubble-wand activities in the 48 to 60 month range (ages 4 to 5), which gives you a sense of how much fine motor control is involved. Younger toddlers can still enjoy bubbles if you blow them or wave the wand through the air to form them without blowing.
Nose Blowing: The Hardest Skill
Learning to blow air through the nose on command is one of the later blowing milestones. Most children start learning between ages 2 and 4, with wide variation. Some toddlers figure it out by 2, often by imitating a parent or older sibling. Others don’t get it until closer to 4.
The challenge is partly physical and partly conceptual. A child has to close their mouth, direct air through the nose, and push with enough force to clear mucus. That’s a complex sequence. Many kids first need to understand the concept of pushing air out at all, which is why speech therapists often recommend starting with mouth-blowing activities (bubbles, pinwheels, tissue) before attempting nose blowing. You can also let your child feel the air coming from your nose when you close your mouth and exhale. That concrete, physical demonstration helps them connect the dots between what you’re asking and what their body needs to do.
Activities That Build Blowing Skills
If your child is in the toddler range and working on blowing, playful practice helps more than direct instruction. The goal is to make blowing feel like a game, not a task. Aim for short sessions of 10 to 15 minutes, once or twice a day, and follow your child’s interest.
- Bubbles: Even before a child can use a wand independently, blowing bubbles from a cup of soapy water with a straw encourages deep breaths and sustained airflow.
- Cotton ball races: Set up a “track” on a table and have your child blow a cotton ball or pom pom from one end to the other using a straw. You can add goals to make it a soccer game.
- Bath boats: In the tub or a washing-up bowl, have your child blow a toy duck or small boat across the water with a straw.
- Musical instruments: Kazoos, recorders, and harmonicas all encourage blowing with different levels of force.
- Pinwheels and windmills: These give instant visual feedback, which is motivating for toddlers who are still learning to direct their airflow.
- Bubble snakes: Cut the bottom off a plastic bottle, cover the opening with an old sock secured by a rubber band, dip it in soapy water, and blow through the top. Long chains of tiny bubbles come out the other end.
- Straw rockets: Tape a paper cone onto a straw, drop a pom pom inside, and blow to launch it. The immediate reward of watching something fly keeps kids engaged.
Why Blowing Matters for Speech
Blowing exercises strengthen the same muscles children use to form words. The lips need to round, purse, and seal to produce sounds like “p,” “b,” “w,” and “oo.” The cheeks need enough tone to direct airflow rather than letting it leak out the sides. And the ability to control how much air comes out, and how fast, directly supports clearer pronunciation. This is why speech therapists frequently include blowing games in their sessions. It’s not about the blowing itself; it’s about building the underlying muscle control that speech depends on.
If your child is past age 3 and still struggles to blow out a candle, blow bubbles, or direct air in any controlled way, it may be worth mentioning to your pediatrician. Delayed oral motor development can sometimes affect feeding and speech, and early support tends to be more effective than waiting.
