When to Talk to Your Pediatrician

Every child develops at their own pace, and a wide range of progress is considered typical. However, if you notice that your child is not meeting several milestones for their age group, or if you have any concerns about their development, it's always a good idea to bring it up with your pediatrician. Early conversations with your child's doctor can help you understand what to look for and when additional support may be helpful.
