Parents Also Ask

When does weak syllable deletion go away?▼

Weak syllable deletion typically resolves by age 4. If your child still drops syllables from familiar words after age 4, consider evaluation. Some complex words may take longer.

Why does my child say "nana" instead of "banana"?▼

Children naturally emphasize the stressed (louder) syllable and drop the unstressed (quieter) one. "Ba-NA-na" → "nana." This is a normal simplification strategy as they learn longer words.

"I enjoy the "Repeat with Reddy" section where the kids can imitate the sounds. It's very easily organized. The stories are a nice touch too."
