This happens when a child breaks a blend (two consonants together) by inserting a vowel sound (usually "uh") in the middle.
What you hear: "Buh-lack" for "Black", "Suh-poon" for "Spoon", "Guh-reen" for "Green".
This is when a child adds a "uh" sound to the end of a word, often to release the tension of the final consonant.
What you hear: "Dog-uh" for "Dog", "Cat-uh" for "Cat", "Red-uh" for "Red".
Check the Speed: Often, "Buh-lue" happens because the child is rushing. Slow them down. "Say it slowly... B...L...ue."
Whisper the Helper: If they are really stuck on "Buh-lue", ask them to whisper the "Buh" and shout the "Lue". This reduces the force of the extra vowel.
Don't Over-Articulate: Sometimes parents cause this! If you say "Look at the D-O-G-uh" (trying to be clear), the child copies the "uh". Make sure you are clipping your sounds short and crisp. "Dog." (Not Dog-uh).
