How to encourage milestone progression
Here are some strategies to encourage your child to talk more and develop a richer vocabulary:
Read to your child: Regularly read books to your child to help them learn new words and understand sentence structures.
Engage in conversations: Talk with your child about their day and ask open-ended questions to encourage them to use language expressively.
Incorporate play-based learning: Use language in play activities, such as naming objects and actions, to make learning engaging, fun, and interactive.
Model correct speech: Repeat what your child says with correct pronunciation and grammar to help them learn correct language and speech.
Developmental progress
Every child is different and develops at their own pace. While developmental milestones provide general benchmarks, it's normal for children to reach them at different times. Some children excel in one area and take their time in others. Factors like temperament, family environment, and biology influence developmental progress. Instead of comparing your child to other children, focus on their patterns of progress.
When to consult your pediatrician
Contact your local or Summer Health pediatrician if your child:
Misses multiple developmental milestones
Shows a noticeable regression in skills (like losing language)
Seems significantly delayed in speech
Shows problems with hearing, vision, or overall health that could impact development
Your pediatrician will refer your child to a developmental specialist or speech-language pathologist for evaluation and support if indicated.
If you have questions about your child’s speech and language development, reach out to your local or Summer Health pediatrician for support. Summer Health is a pediatric telehealth platform offering 24/7 care, providing answers for everything from urgent concerns to everyday questions about your child’s health.
