Once upon a time, in a small house, there lived a little boy named Tim. Tim was a happy boy who loved to play with his toys. One day, Tim discovered something different in his mouth. He felt a tiny tooth with his tongue. It was a new tooth! Tim was so excited, he ran to his mom.
"Mom, I found a new tooth in my mouth!" Tim said, showing his mom the new tooth. His mom looked and smiled. "Wow, Tim! That's great! Your new tooth is growing in!"
The next day, Tim went to play with his friend, Lily. He told her about his new tooth. Lily felt her mouth and found a new tooth too! They both were so happy to have something different in their mouths.
Every day, Tim and Lily checked their new teeth. They grew bigger and stronger. Tim and Lily were proud of their new teeth and couldn't wait to show them off to their friends. They knew that having new teeth was a special part of growing up.
