<human>:  How can I teach my baby to say certain words?
<bot>: To teach your baby to say certain words, start by saying the word clearly and slowly when the baby is paying attention. Use an encouraging tone of voice and facial expressions. You can also model using the word in a sentence. If your baby is not repeating the word, try presenting it in a different context or a different way. You can also provide positive reinforcement when the baby uses the word, like praising or giving a desired object. Practicing and repetition are important when teaching words, so keep repeating the word frequently during daily activities.
