Final answer:
Babbling is an important step before cooing in the development of infants' ability to speak and understand language.
Step-by-step explanation:
True. Babbling is indeed an important step that occurs before cooing as infants develop their ability to speak and understand language. Babbling refers to the repetitive sounds and syllables that infants make, which helps them practice the motor skills necessary for speech production. Cooing, on the other hand, is the production of vowel-like sounds such as 'oo' and 'goo', and typically occurs before the development of consonant sounds in babbling.
