Ensuring your child is progressing developmentally is crucial for their overall well-being and future success. Early detection of delays allows for timely intervention, fostering skills in speech, motor functions, and social interactions. By monitoring their growth, you can help your child reach their full potential and navigate each developmental milestone with confidence. We expect to see the following milestones for infants ages 9 to 12 months:
