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 children’s fine motor skills begins when they start to write and use scissors; in fact, fine motor skills can be observed from an infant’s grasping abilities. In most cases, a 5-month-old child is able to hold a block in each hand; a 1-year-old child can use the index finger and thumb to grasp small objects; at the age of 2, children can vertically stack 6 blocks; at the age of 3, children can string together small beads; and at the age of 4, children can use scissors to cut paper along a line and in a circle.

Speech and Language

If your child exhibits any of the following conditions, a speech and language assessment is highly suggested:

  • The 1-year-old baby has little eye contact or shows no interest in playing sounds.
  • The child makes sounds or words and can only express but their immediate needs at the age of 2
  • The child cannot understand basic conversations at the age of 3
  • The child is unable to pronounce 85-90% of the sounds clearly at age of 4.
  • He or she has poor social skills with problems understanding others and expressing her/his own opinions.


Other speech difficulties such as stuttering, hoarseness, uncoordinated oral movements, and difficulty swallowing Please contact your speech therapist for further information and assistance.  

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 behavior are a critical foundation of learning for infants and toddlers. If the child is not meeting the cognitive developmental milestones for his or her age, such as he or she does not understand the simple instruction at 2 years, or he or she is not able to name the shape or color at 4 years, it is important to pay attention for the potential of developmental cognitive delay.
