Babies usually start blowing raspberries between the ages of four and six months (1). It is the phase when the baby will also begin cooing and gurgling. It is common for some babies to begin blowing or pouting raspberries earlier or later, and some may not do it at all. As long as your baby is achieving their vital developmental milestones, it is okay if they blow raspberries later or avoid doing it.

Babies may usually blow raspberries as part of their language development. It lets the baby exercise by tapping their tongue and lips and allows them to experiment with all the sounds they can make with them (2). Thus, blowing raspberries is a form of vocal play, and is similar to other types of play that help an infant polish their abilities through games and activities.

Another reason why babies blow raspberries is to gain attention. Babies between the ages of four and six months often respond to sounds by making sounds and make various sounds to gain parents’ attention (3). They may repeatedly try it to gain attention and entertain themselves by the reaction it elicits from others.

Studies indicate that parental responses to the actions and sounds made by the baby influence positive cognitive and social development (6).

How To Respond When A Baby Is Blowing Raspberries?

Blowing raspberries is part of the baby’s normal development, and it is okay to encourage it. Below are some ways to respond to a baby who is blowing raspberries (2).

  1. Imitate the baby: It is your turn to blow raspberries back at them in response. Apart from imitating the raspberry sounds, also mimic the baby’s other sounds to stimulate language development.

  1. Respond uniquely: Set aside a unique sound to respond to your baby blowing raspberries. It can help the baby blow raspberries in the context of communication until they can speak. 
  1. Speak to them: The more you talk to your child, the better they learn how to form sounds. Speak to your little one each time they blow raspberries. Talk to them about your day, describe what you are doing, and even ask questions. Respond positively if they answer back with blowing raspberries or cooing sounds.

Infant-directed speech, also known as baby talk, has an effect on the intersensory perception of fluent speech, as a result of which children may understand the relationship between auditory and visual speech (7).
  1. Sing to your baby: Maintain a dedicated song or nursery rhyme that you can sing when the baby begins blowing raspberries. Encourage them to join you along, even if it is through cooing and blowing raspberries sounds.

  1. Encourage new sounds: You can even make new sounds and encourage the baby to mimic you. Every new sound helps the baby experiment with different mouth movements, flexing the oral muscles and strengthening them.

Blowing raspberries together also offers a great opportunity for parent-baby bonding. Make sure you maintain eye contact so that the baby is completely engaged.

Blowing raspberries usually coincides with the baby’s early language development and could play a role in it. It may provide the following benefits to a baby (4) (5).

  1. Exercise the facial muscles: To blow a raspberry, the baby sticks out the tongue, puckers the lips around it, and pushes the air out. Several voluntary actions happen here, letting the baby exercise control over facial muscles, which play a vital role in speech. In time, it could even help them purse their lips around a spoon or a sipper.
  1. Learn voice control: Babbling, cooing, and blowing raspberries encourage experimentation with voice control. It could help the baby understand that they can manipulate the voice’s pitch, which is vital when we speak words.
  1. Experiment with cause and effect: Some babies may blow raspberries only to check the reaction it elicits from caregivers, siblings, and other family members. A baby may act amused or giggle once you respond positively to blowing raspberries. It is the first step towards learning cause and effect, and understanding the world through experimentation.
  1. Improve parent-baby bonding: Since the baby often blows raspberries to interact with the parents, it could improve their bonding. Blowing raspberries is also a great conversation starter for the parent. It encourages activities that parents and babies can try together.

Frequently Asked Questions

1. Is blowing raspberries a milestone?

Blowing raspberries is a fun and beautiful milestone that precedes beautiful phases of babbling and then talking. However, many children skip this milestone and directly begin to babble. If your baby does not use their lips and mouth to make sounds, even at around six months old, consult a doctor (3).

2. How do I stop my baby from blowing raspberries while eating?

If your baby keeps spluttering food by blowing raspberries while eating, give them a gentle but firm reminder that it is not allowed. It sends a message that you will not offer another bite if they keep spitting food. If they continue the behavior, you may pull the spoon and avoid offering them food for a minute or two.

Blowing raspberries is a fun exercise that may support the development of the baby’s verbal skills. Parents can encourage newborns to blow raspberries as early as four to six months of age and even teach them how to utilize it for communication. So, when you see your baby sticking their tongue out at you, imitate them and use this time to boost your bond with them. This activity promotes exercising a baby’s facial muscles and soothing sore gums, and enhances the natural process of inhaling and exhaling air (breathing), among other benefits. However, consonant sounds and simple phrases will progressively replace blowing raspberries as your infant grows older.
