However, keep in mind:
* This is just a general guideline. Some babies may start babbling earlier, while others might not speak their first word until after 18 months.
* There's a wide range of "normal". If your child is not speaking their first word by 20 months, it's best to talk to your pediatrician.
* Other milestones matter too. While speaking is important, other developmental milestones (like crawling, walking, and interacting with others) are also crucial.
It's important to remember that every child is unique, and there's no one-size-fits-all timeline. If you have any concerns about your child's development, don't hesitate to talk to your pediatrician.
