babbling

Explanation:

These sounds tend to disappear from usage during the babbling stage of language development in children. This stage is part of the language acquisition process in which an infant appears to begin experimenting with language by uttering very articulate sounds that share a similarity with the language they are learning, but are still unrecognizable. Most times this is a precursor to language development but other times it is the child simply experimenting with vocal sounds.
