Observe your child — Observing your child carefully when he babbles will let you know if his babble is meant to send you a message or not. If you observe your child babbling while he is busy playing and not trying to get your attention, it may be that your child is playing with sounds and practicing his new skills. This might motivate him to babble again, and this could turn into a game of copycat!
They also encourage your child to intentionally make sounds to get your attention. This will eventually build his vocabulary. If your child is not babbling… If you think your child is late to start using sounds or babble, talk to a speech language pathologist, who can evaluate whether this is cause for concern.

They can produce single syllables with precise timing, but often produce reduplicated babble , making forms like [dada] , [guhguh] or [baba] and even longer chains, like [dadadadada].
When it first appears in this period, it usually has no communicative function. That is, infants do not appear to use it to refer to events or objects in the environment. However, at the same time as these vocal developments are taking place, parallel developments can be seen in babies arm movements, which they also now start to make repeatedly and rhythmically.
So two types of rhythmic movements of arms and oral articulators are developing simultaneousy , and it is possible both phenomena are connected. The emergence of babble has been studied in babies all over the world and findings suggest that, at first, they produce similar sounds regardless of which language s they have been hearing. This synchrony in developments suggests that the onset of babbling is closely related to speech perception.
Scientific studies indicate that when children can produce a canonical syllable, e. In any case, as a prerequisite to start babbling, babies need, from the first weeks of life, to hear adults talking around them and directly to them.
