Final answer:
Babies begin to create consonant babble sounds during the babbling stage of language development, usually around 6 months old. This stage precedes the baby's ability to say their first words with meaning.
Step-by-step explanation:
Babies begin to create consonant babble sounds during the babbling stage of language development. Babbling typically starts when babies are around 6 months old. During this stage, babies produce repetitive single syllables that include consonant sounds, such as ma-ma, da-da, or ba-ba.
It is important to note that babies replicate sounds from their own languages. So, a baby whose parents speak French will babble in a different way than a baby whose parents speak Spanish or another language.
This babbling stage is an important step towards language development, as it precedes the baby's ability to say their first words with meaning at around 12 months old.
