Child Development Milestones

A child typically meets developmental milestones at a specific age. A guide to normal childhood development milestones can help you recognize when your child might need professional attention. If your child is not meeting expected milestones, Tri-County Therapy recommends seeking additional information from one of our licensed therapists.

Articulation & Phonology

Articulation is how a sound is made using accurate and coordinated movement of the jaw, lips, tongue, teeth, and soft palate. Articulation is also impacted by voice, the ability to use breath and contraction of the vocal folds to create sound, and fluency, the rhythm and flow of speech. Phonology refers to the patterns of sound production, and phonological disorders refer to simplification strategies that children use to make speech production easier.

Fine & Gross Motor

The ability to use large and small muscle groups that coordinate body movements involved in activities such as walking, running, jumping, throwing, writing, maintaining balance, buttoning, cutting, visual tracking, and tracing.

Language Development

The process by which children come to understand and communicate language during early childhood. Receptive language includes a child’s ability to listen to, interpret, and understand symbolic communication. Expressive language includes a child’s ability to effectively and completely express their wants, needs, thoughts, ideas, and emotions by talking.

Sensory Development

The maturing of the five familiar senses: hearing, smell, taste, touch, and vision. It involves the way your child’s nervous system receives input from these senses and then forms an appropriate motor or behavioral response, also known as sensory processing.

Social Skills

The skills we use to communicate and interact with each other, both verbally and non-verbally, through gestures, body language and our personal appearance.
