Child Developmental Delay

Gross Motor Skills

Gross motor skills refer to large bodily movements, such as rolling over, crawling, kneeling, standing, and walking that develop during infancy, to jumping, going up and down stairs, running, and more complex hand-feet and hand-eye coordination that develop throughout the toddler and preschool ages. Delays in gross motor skills may cause difficulty in other abilities (e.g. fine finger movements, coordination of lips and teeth) and affect subsequent learning and development.

Fine Motor Skills

It is often thought that the development of fine motor skills begins when children begin to write and use scissors; in fact, fine motor skills can be observed from an infant’s grasping abilities: a 5 month old is able to hold a block in each hand, and a 1 year old can use the index finger and thumb to grasp small objects. At 2 years old, children can vertically stack 6 blocks, at 3 years they an string together small beads, and at 4 years, children can use scissors to cut along a line and in a circle.

Language and Expression

“At 1 year old, the child does not look at the person who is speaking and has no intention to speak. The child is unable to say 50 words at the age of 2, combine words at 2.5 years, understand basic conversation at the age of 3, has not seen an improvement in articulation at age 4, and has social difficulties owing to problems with understanding and expressing language.” If your child exhibits any of the above, a language development assessment is highly recommended. Early detection and intervention is key to help them improve faster!

Other speech difficulties: Please ask your speech therapist for more information and assistance about other speech problems such as stuttering, hoarseness, uncoordinated oral movements, and difficulty swallowing.

Social Emotional

From a very early age, infants and young children begin to express their own emotions and needs, show interest and interact with others, and learn to understand the emotions of others. These behaviors are related to future interpersonal interactions, moral values, and ability for emotional regulation. If infants and young children are frequently angry, unable to understand the emotions of others, and uncooperative in groups, it is important that they receive evaluation and treatment by professional staff as soon as possible.


The various sensory experiences and exploratory behaviors displayed by infants and young children during development are important foundations for learning. If you observe cognitive abilities that infants and young children should have, but have not developed at a certain age, such as the inability to understand simple instruction at 2 years old or name shapes and colors at 4 years old, it is important to pay attention whether there is risk of cognitive developmental delay.
