Long before infants speak recognizable words, they produce a number of vocalizations. Describe some of these vocalizations in the order that they appear in infants.
What will be an ideal response?
Babies' sounds or vocalizations go through this sequence during the first year:
1) Crying: Babies cry even at birth. Crying can signal distress, but there are different types of cries that signal different things.
2) Cooing: Babies first coo at about 2 to 4 months. These are gurgling sounds that are made in the back of the throat and usually express pleasure during interaction with the caregiver.
3) Babbling: In the middle of the first year, babies babble-that is, they produce strings of consonant-vowel combinations, such as "ba, ba, ba, ba."
