What is going on
Backing is the mirror image of fronting: the child replaces tongue-tip sounds like /t/ and /d/ with back-of-the-tongue sounds like /k/ and /g/. "Tea" comes out as "key," and "Daddy" becomes "Gaggy."
Backing is the one pattern on this list that is not part of typical development. Unlike fronting or stopping, no stage of normal speech includes it. It is more often seen alongside other atypical patterns, and it is worth a full evaluation rather than home practice, and it tends to be more resistant to treatment than the typical processes.
