Research has shown that by as early as 5 months, infants are more emotionally receptive to child-directed speech. This is because it is typically higher-pitched, slower, and more exaggerated in its intonation, which is more engaging for infants.

Note: Choice A is false as deaf mothers have been found to use a similar style of communication called "visible child-directed speech" that relies on facial expressions and gestures. Choice C is not entirely accurate as infants may continue to show a preference for child-directed speech beyond age 2. Choice D is partly true as child-directed speech does become more emotion-laden, but it also becomes more information-laden as caregivers use it to teach and explain things to their children.
