Here's why:
* Age: Babies and toddlers learn words at a much faster rate than older children.
* Individual Differences: Some children are naturally faster language learners than others.
* Exposure: The amount of language a child is exposed to greatly affects their vocabulary growth.
* Learning Style: Some children learn best through hearing words, while others learn through seeing them written or through play.
However, here are some general estimates:
* Babies: From about 6 months to 18 months, babies are in a rapid word-learning phase. They may learn several new words each week.
* Toddlers: Toddlers (18 months to 3 years) may learn a few new words per day.
* Preschoolers: By preschool age, children might learn a few new words per week.
Instead of focusing on a specific number, it's more important to focus on creating a rich language environment for your child. This means:
* Talking to them regularly.
* Reading to them often.
* Playing games that involve language.
* Exposing them to different languages and cultures.
Remember, every child develops at their own pace. Focus on fostering a love of language and providing a supportive environment for their growth!
