Important Note
These milestones are general guidelines. Every child develops differently, and there is a wide range of what is considered typical. Cultural and linguistic differences can also influence the timeline of development. If you have concerns about your child's speech or language, consulting with a licensed speech-language pathologist is the best way to get personalized guidance.
