L

To produce the /l/ sound, have your child tap their tongue right behind their top, front teeth.  For the /l/ sound, have your child slowly move their tongue up to the spot and back down again.  While they're doing this, have him hum or turn their voice on.

If your child is having trouble figuring out where to put their tongue, use these techniques to show them the right place:

• Touch the spot right behind the top, front teeth with a popsicle stick or sucker.  Then tell them to put their tongue in the same spot.
• Put a sticky food, like peanut butter or marshmallow cream, on the spot right behind their top, front teeth.  Then, have them lick it off.  When you are describing that spot again, call it the sticky spot.

Below are words to practice.  Try using words in silly sentences.  Have fun!
